Hattusa

Hattusa was, for almost half a millennium, the beating heart of the Hittite Empire — a Bronze Age superpower that stood shoulder to shoulder with Egypt, Assyria and Babylon, and at times surpassed them all. Spread across nearly 1.8 square kilometres of windswept ridges in north-central Anatolia, the city rose in the 17th century BC on a hill above the Budaközü stream, was rebuilt and expanded by generations of kings, and was finally consumed by fire and forgotten around 1180 BC. Behind massive cyclopean walls more than six kilometres long, monumental gateways once guarded by lions, sphinxes and a striding warrior god opened onto a Lower City of temples and craftsmen and an Upper City crowded with more than thirty sanctuaries. Beneath the rampart of Yerkapı runs a corbelled stone tunnel still passable today, while two kilometres to the east, the open-air sanctuary of Yazılıkaya carries the largest known procession of Hittite gods carved directly into living rock. The royal citadel of Büyükkale once held an archive of more than thirty thousand cuneiform tablets — written in Hittite, Akkadian, Hurrian, Hattic, Luwian and Sumerian — among them the silver-tablet treaty that ended the war between Hattusili III and Ramesses II of Egypt, the oldest international peace treaty known to history. Rediscovered in 1834, identified in 1906 and excavated continuously since, Hattusa was inscribed on the UNESCO World Heritage List in 1986 and remains one of the most evocative archaeological landscapes in the world.

Why Hattusa Matters

Few archaeological sites in the world fuse political, religious, linguistic and architectural significance the way Hattusa does.

To stand at the Lion Gate or the rim of Yerkapı is to look out over a landscape that was, in a very literal sense, one of the four corners of the Late Bronze Age world.

For half a millennium, the orders that left this hilltop shaped events from the Aegean coast to the upper Tigris, and from the Black Sea to the deserts of Sinai. Modern visitors who walk the long circuit of Hattusa today are tracing the topography of imperial power.

The reasons the city matters are many. The seven that follow are perhaps the most important.

1. Capital of a Bronze Age superpower. From roughly 1650 to 1180 BC, Hattusa was the seat of the Hittite Great Kings — sovereigns who corresponded with the pharaohs of Egypt and the kings of Babylon as equals, and who at the Battle of Kadesh in 1274 BC fielded one of the largest chariot armies in recorded history. They controlled an empire that, at its greatest extent under Suppiluliuma I, stretched from the western edge of Anatolia to the upper Euphrates and from the Black Sea coast deep into Syria.

2. The world's first peace treaty. The Treaty of Kadesh, concluded in 1259 BC between Hattusili III and Ramesses II, survives in both its Hittite cuneiform and Egyptian hieroglyphic versions. A replica of the Hittite text hangs in the headquarters of the United Nations in New York as a foundational document of international diplomacy. No other surviving Bronze Age document so clearly anticipates the language of modern international law.

3. The cradle of written Indo-European. Hittite — the language of the royal court and chancery here — is the earliest Indo-European language preserved in writing, predating Mycenaean Greek by several centuries. Without Hattusa, the comparative study of Indo-European languages would be missing its earliest chapter. The decipherment of Hittite by Bedřich Hrozný in 1915 stands beside Champollion's reading of hieroglyphs as one of the great triumphs of historical philology.

4. A monumental archive. More than 30,000 cuneiform tablets and fragments have been recovered from Büyükkale, the Great Temple and the Upper City. They include treaties, laws, royal annals, oracle inquiries, festival rituals, mythological poems and even fragments of the Epic of Gilgamesh. The archive was inscribed on the UNESCO Memory of the World register in 2001 — a recognition that the site is, in a sense, a double World Heritage.

5. Living rock as canvas. At Yazılıkaya, two natural rock chambers were transformed into an open-air pantheon. Nowhere else in the Hittite world is the divine procession of the empire so completely preserved. Sixty-four gods, two great rock-cut reliefs of king-and-god, and the strange dagger-god of Chamber B form a composition without parallel in the religious art of the Bronze Age.

6. A masterclass in Bronze Age engineering. The casemate walls, the artificial pyramidal embankment at Yerkapı, the 71-metre stone-corbelled postern tunnel, the great grain silos and the dammed reservoirs together form one of the most ambitious fortification and urban-infrastructure programmes of the second millennium BC. Hittite engineering can be measured against any in the ancient world.

7. A UNESCO World Heritage Site since 1986. Inscribed under criteria (i), (ii), (iii) and (iv), Hattusa is recognised as a masterpiece of human creative genius, a cradle of cultural exchange across Anatolia, Mesopotamia, Syria and Egypt, and an exceptional testimony to a vanished civilisation. Its outstanding universal value is officially recognised, and access to the site is supported by an active state programme of conservation and presentation.

A note on names

A reader new to the subject can easily get lost among the different names used for this site. A short glossary may help.

• Hattus / Hattusa / Hattusha / Hattuša / Boğazköy / Boğazkale. All refer to the same place. Hattus is the early Hattic name; Hattusa is the Hittite form, sometimes spelled Hattusha or, with the proper diacritic, Hattuša. Boğazköy is the older Turkish name of the modern village ("village of the gorge"); Boğazkale is the current administrative name of the district.
• Hatti. The country of which Hattusa was the capital. Egyptian and Assyrian sources call the Hittites the people of Hatti.
• Nesa / Kanesh. An earlier capital, located at modern Kültepe near Kayseri. The Hittites called their own language Nesite, after this city.
• Hittites vs Hatti. A confusing pair of terms — see the FAQ below for the distinction.

Geography and Setting

Hattusa lies in the modern district of Boğazkale, in Çorum Province, on the high plateau of north-central Anatolia.

The site is roughly 200 kilometres east of Ankara and about 80 kilometres south-west of the provincial capital, Çorum. Most visitors approach from the Ankara–Samsun highway, leaving the main road at Sungurlu and following 30 kilometres of country road across rolling fields and pine-clad hills.

The ancient city sits at an altitude of about 1,000–1,250 metres, climbing from the Lower City near the Büyükkaya rock to the southern heights of Yerkapı. This is steppe-and-mountain country — open, exposed and breathtakingly clear when the weather is kind.

The town of Boğazkale, a quiet village of a few hundred households, lies just below the Lower City. A museum, a handful of guesthouses and a couple of family restaurants serve travellers from there. Beyond the village, the road climbs steeply into the ancient city itself.

Why this site, of all sites?

Three features made this spot ideal for a capital.

Defensible terrain. The site occupies a long ridge sliced by deep gorges. To the north and west, sheer cliffs fall away to the Budaközü stream, a tributary of the Delice that ultimately feeds the Kızılırmak — the longest river entirely within Türkiye. To the east rise rocky outcrops crowned by natural citadels — Büyükkale, Sarıkale, Yenicekale and Büyükkaya. The Hittite engineers exploited every escarpment, knitting wall and bedrock together so that, in some stretches, the fortifications are little more than a parapet along a natural cliff.

Water and farmland. The Budaközü provided year-round water, while the surrounding plateaus supported wheat, barley and pasture for the city's enormous flocks. Hittite texts describe the king inspecting royal estates that surrounded Hattusa for many days' march in every direction. Pollen and seed analyses from the site confirm a managed landscape of cereals, vines, fruit trees and woodland.

Central position in Anatolia. Hattusa stood at a crossroads between the Black Sea, the Aegean, the Mediterranean and the Euphrates valley. Caravans, armies and messengers could leave the capital and reach any of the empire's frontiers within weeks. The same centrality, however, also exposed the city to threats from every direction — most dangerously the Kaška peoples of the Pontic mountains to the north.

Climate

The climate at Hattusa is classically continental:

• Winter: cold and often snowy, with night-time temperatures regularly below −10 °C and snow lying on the upper ramparts for weeks at a time.
• Spring: short and brilliant, with carpets of wildflowers on the steppe and fast-melting snow filling the Budaközü.
• Summer: hot and dry, with daytime highs of 30 °C or more under a hard blue sky and almost no shade.
• Autumn: clear, crisp and golden, with the limestone glowing in the angled light and the surrounding fields turning to stubble.

The best seasons for a visit are mid-April to mid-June and mid-September to late October, when the temperatures are pleasant, the wildflowers or autumn colours add to the atmosphere, and the angled light brings out every relief in the limestone.

Modern Boğazkale

The modern village of Boğazkale (formerly Boğazköy, "the village of the gorge") lies at the foot of the ancient city. Its quiet streets are lined with low stone houses, vegetable gardens and the occasional Hittite-style sculpture set up as a roadside ornament. A small population — fewer than 1,500 inhabitants — lives largely from agriculture and from tourism. The district was elevated to its present administrative status precisely to support the management of the archaeological site.

For visitors, Boğazkale provides:

• A handful of family-run guesthouses and small hotels;
• Two or three village restaurants serving Çorum specialities (Çorum mantı, lamb stews, the famous Çorum leblebi roasted chickpea);
• The Boğazkale Museum with its concentrated, high-quality collection;
• A modest visitor centre at the main gate of the archaeological site.

It is a charming, undeveloped base from which to explore one of the great archaeological landscapes of the world.

Historical Timeline

The history of Hattusa unfolds over more than four millennia, from a humble Hattic village to the burning capital of an empire and on into half-forgotten Byzantine and Ottoman afterlives. The major phases are summarised here.

Early Bronze Age (c. 3000–2000 BC) — The Hattic Settlement

Long before the arrival of the Hittites, the hill above the Budaközü was occupied by a people the cuneiform sources later call the Hatti. They spoke a non-Indo-European language preserved only in fragments — most of it embedded in later Hittite ritual texts — and they gave their name to the city, the country and, by extension, the later empire.

Their settlement at this spot is attested by pottery, hearths and the foundations of mudbrick houses on the Büyükkaya outcrop and in the Lower City. Hattic religious practice, especially the cult of the storm god and the sun goddess, would later become the backbone of Hittite state religion.

By the late third millennium BC, Hattic Hattus had become a regional centre with its own king, craftsmen and temples. Imported objects — Syrian seals, Anatolian metalwork — show that even at this early date the settlement was tied into long-distance networks of trade.

Middle Bronze Age — The Assyrian Trade Colony Era (c. 1950–1750 BC)

In the early second millennium BC, Assyrian merchants from the city of Ashur established a network of trading posts (kārum) across central Anatolia.

The most famous is Kültepe-Kanesh near modern Kayseri, but a smaller kārum existed at Hattusa as well, on the lower slopes of the city. From this period come the first written sources connected with the site — cuneiform tablets, in Old Assyrian, that record loans, marriages and tin-and-textile caravans. They also preserve the city's Hattic name, Hattus, and document a network of local princes whose petty kingdoms the Hittites would soon swallow up.

The Assyrian kārum system collapsed around 1750 BC, but it left behind two crucial legacies:

• The introduction of cuneiform writing into Anatolia, which the Hittites would adopt for their own language.
• The first detailed picture of the political geography of central Anatolia, including the first attested mentions of Hattus.

Around 1700 BC, Anitta of Kussara, an early Indo-European-speaking king, conquered Hattus, burned it to the ground and laid a famous curse on the site:

Whoever after me shall become king and resettle Hattusa, may the storm god of heaven strike him.

The curse, recorded on a later tablet known as the "Anitta Text," did not hold.

Hittite Old Kingdom (c. 1650–1500 BC) — Hattusili I and the Foundation of the Capital

Within a generation of Anitta's curse, an ambitious ruler from the same dynastic line — Hattusili I — defied tradition and made Hattus his capital, renaming it Hattusa and renaming himself "the man of Hattusa."

This is the act that founds Hittite history as we know it. Hattusili campaigned south-east into Syria, attacking Alalakh and Yamhad and bringing back the first great influx of foreign craftsmen, scribes and gods.

His grandson and successor, Mursili I, extended these campaigns dramatically: around 1595 BC he raided Babylon itself, sacking the city of Hammurabi's heirs and ending the First Dynasty of Babylon — one of the longest-range military operations of the entire Bronze Age.

Old Kingdom Hattusa was already a planned, walled city. The earliest casemate walls, the first version of the Great Temple in the Lower City, and the original palace complex on Büyükkale all belong to this phase. The royal court was already using cuneiform, primarily in Akkadian for diplomatic letters and increasingly in Hittite for internal administration.

Hattusili I's "Testament" — a remarkable text in which the dying king reflects on his sons' failings and designates a successor — is one of the earliest documents of political autobiography in world literature.

Hittite Middle Kingdom (c. 1500–1400 BC)

The Middle Kingdom is a comparatively obscure period of internal struggle, regicide and territorial loss.

The Kaška peoples of the Pontic mountains repeatedly raided down into the Hittite heartland, at one point even sacking Hattusa itself. The Hurrian kingdom of Mitanni, expanding from northern Mesopotamia, encroached on Hittite Syria. Kings such as Tudhaliya I/II and Arnuwanda I patched the empire back together and laid the foundations for the great expansion to come.

It was probably during this period that the older fortifications around the Lower City were strengthened and extended, and that the political institutions of the Hittite state — including the so-called pankuš, an assembly of noble warriors — took their classic form.

Hittite Imperial / New Kingdom (c. 1400–1180 BC)

The "Empire period" is the age of the great names that history books still remember.

Suppiluliuma I (c. 1344–1322 BC) — perhaps the greatest Hittite king. He destroyed the Mitanni kingdom of the upper Euphrates, planted his sons as kings in Aleppo and Carchemish, and at one point was offered the hand in marriage of an Egyptian queen widowed by Tutankhamun — an episode known as the "Zannanza affair," which ended badly when his son was murdered en route to Egypt.

Mursili II (c. 1321–1295 BC) — author of the so-called "Plague Prayers." These are extraordinarily personal religious texts asking the gods to lift an epidemic that had ravaged Hatti for twenty years. They show a king pleading directly with his gods in language of striking sincerity.

Muwatalli II (c. 1295–1272 BC) — the king who fought Ramesses II at Kadesh in 1274 BC. For reasons that are still debated, he briefly moved the capital south to Tarhuntassa, leaving Hattusa to be administered by his brother Hattusili.

Hattusili III (c. 1267–1237 BC) — usurper, statesman and diplomat. He overthrew his nephew Urhi-Teshub and seized the throne; the act haunted him and is justified, at length, in his remarkable "Apology" — one of the earliest pieces of political self-defence in world literature. He was the architect of the Treaty of Kadesh, and the husband of the formidable queen Puduhepa, herself a powerful diplomat and religious reformer.

Tudhaliya IV (c. 1237–1209 BC) — religious reformer and great builder. He is responsible for most of the Upper City temples, for the rebuilding of the Great Temple, and for the final form of the Yazılıkaya sanctuary, where his portrait is carved in close embrace with his patron god Sharruma.

Suppiluliuma II (c. 1207–1180 BC) — the last Great King. He led naval campaigns against Cyprus, fought the Assyrians in the east, and tried to hold together an empire under siege from every direction. He is also the most likely author of the long Nişantaş inscription in the Upper City.

It was under these kings that Hattusa took on the monumental form we see today. The Upper City was enclosed by new walls; more than thirty temples were laid out in a vast sacred quarter; the Lion Gate, the King's Gate, the Sphinx Gate and the Yerkapı embankment were completed; the postern tunnels were driven through the ramparts; and the royal archives on Büyükkale grew to the tens of thousands of tablets that modern excavators have recovered.

The Battle of Kadesh (1274 BC) and the Treaty (1259 BC)

In May 1274 BC, the Hittite king Muwatalli II and the Egyptian pharaoh Ramesses II met on the plain of Kadesh on the Orontes, in modern Syria.

Ramesses, ambushed by Hittite chariotry and cut off from his main army, narrowly avoided catastrophe and turned a near-defeat into a heroic propaganda victory, plastering the temples of Egypt with scenes of his personal valour. The Hittites took Kadesh and a generation's worth of Syrian dominance.

Estimates suggest more than 5,000 chariots took part on the two sides — making Kadesh quite possibly the largest chariot battle in history. The Hittite three-man heavy chariot proved a match for the lighter Egyptian two-man chariot at close quarters.

Fifteen years later, faced with the rising power of Assyria to the east and continuing tensions to the south, Hattusili III and Ramesses II negotiated a formal peace. The treaty was inscribed on tablets of silver, exchanged between the courts, copied onto clay for the archives, and carved in hieroglyphs on the walls of the Egyptian temples of Karnak and the Ramesseum.

It is the oldest known international peace treaty in human history.

Collapse (c. 1190–1180 BC)

Around 1180 BC the great city was burned and abandoned.

The destruction layer is visible all over Hattusa — collapsed mudbrick, scorched timbers, broken pithoi — but its causes are still debated. The most likely explanation is a perfect storm:

• pressure on the frontiers from the so-called Sea Peoples, who at the same moment were tearing through the Levant and bringing down the kingdoms of Ugarit and Carchemish;
• prolonged drought and famine documented in late Hittite and Egyptian letters that beg for grain shipments — recent tree-ring evidence from Anatolia confirms a severe dry spell at exactly this date;
• internal political crisis, perhaps culminating in dynastic civil war;
• the breakdown of long-distance trade networks that supplied tin, copper and luxury goods to the entire eastern Mediterranean.

Recent excavations suggest that the royal court may have evacuated the city, removing the most valuable cult objects and archives, before squatter occupation and a final conflagration ended Hattusa as a functioning city. The pattern of destruction is more consistent with planned abandonment than with surprise attack.

Dark Age and Phrygian Occupation

For roughly four centuries after the collapse, Hattusa was a near-empty ruin.

In the early first millennium BC, a modest Phrygian village reoccupied the Büyükkaya ridge, exploiting the broken walls and rebuilding small houses in the shadow of the ruined gates. Phrygian pottery, fibulae and small bronzes have been found across the site. Some of the Phrygians may have been descendants of the original Hittite population; others were newcomers from western Anatolia.

The Phrygians appear to have remembered something of the city's old sanctity. Several Hittite cult niches were reused, and a small Phrygian shrine was installed in the former temple precinct of the Upper City.

Galatian, Roman, Byzantine and Seljuk Eras

In the third century BC, Galatian Celts settled in central Anatolia, and the Hattusa region passed into their territory. Under Roman rule, the area became part of the province of Galatia; scattered Roman farmsteads and milestones have been documented in the surrounding valleys.

During the Byzantine period, a small fortified settlement and a church rose on Büyükkale, reusing Hittite ashlar masonry. A Byzantine cemetery with simple stone-lined graves has been excavated within the ruins of the old palace.

Finally, under Seljuk and Ottoman rule, the village of Boğazköy — "the village of the gorge" — grew up below the ancient walls. Its inhabitants ploughed up cuneiform tablets and carved blocks for centuries before scholars realised what they were. Local memory preserved place-names — Aslantaş ("lion stone") for the Lion Gate, Yazılıkaya ("inscribed rock") for the sanctuary — that would help later European travellers locate the monuments.

Major Monuments

A visit to Hattusa is structured by a roughly 6-kilometre one-way road that loops up from the Lower City around the Upper City and back. The major monuments are described here in the order most visitors meet them.

The Lower City and the Great Temple (Temple I)

The Lower City spreads across a relatively gentle slope just below the modern village.

Its dominant structure is the Great Temple, also called Temple I, the largest and best-preserved Hittite temple known. Built in its final form under Hattusili III and Tudhaliya IV in the 13th century BC, the complex covers more than 14,500 square metres.

At its heart stand two adjacent cult chambers, each entered through a complex sequence of courts and porticoes. The two cellas were dedicated to the supreme deities of the Hittite state pantheon:

• The Storm God of Hatti (Teshub / Tarhunna) — the great male sky god, chief of the Hittite-Hurrian pantheon.
• The Sun Goddess of Arinna (later identified with Hepat) — "Queen of Heaven and Earth," patroness of the royal house.

Around the temple lie row upon row of storerooms — at least 82 of them — whose floors were once crowded with monumental pithoi for grain, oil and wine, and whose shelves held administrative tablets recording the daily life of the sanctuary. One pithos found intact could have held over a thousand litres.

The temple precinct includes the famous green stone — a block of polished serpentinite, almost cubic, set into a low platform near the entrance to the cult chambers. Its function is uncertain; suggestions include a ritual washing basin, a base for a statue, or a diplomatic gift from the king of Egypt. Local legend treats it as a wishing stone, and the green block has become the unofficial emblem of the site.

Beyond the Great Temple stretch the workshops and residential quarters of the Lower City, where craftsmen, priests, scribes and ordinary citizens once lived in mudbrick houses around small courtyards. Several of these houses have been partially excavated, and their layout gives a vivid impression of urban life in a Bronze Age capital.

The Lion Gate (Aslanlı Kapı)

The Lion Gate stands at the south-western corner of the Upper City walls.

Two great limestone lions, carved in high relief from the gate jambs themselves, rear out of the masonry on either side of the entrance, mouths open in a perpetual roar.

The lions are works of mature 13th-century BC Hittite sculpture — broad-shouldered, frontally posed, with ferocious incised manes. They served simultaneously as:

• Apotropaic guardians warding off evil spirits and ill fortune;
• A clear visual statement of royal authority to anyone approaching the city;
• A reminder of the king's role as "strong lion" in Hittite royal titulature.

The gate itself was a typical Hittite parabolic structure: two great stone jambs leaning slightly inward and meeting in a corbelled arch (now lost). The wooden doors that once closed it would have been faced with bronze.

The right-hand lion is the better preserved of the two and is among the most photographed images of Hittite art anywhere in the world.

The King's Gate (Kral Kapı)

At the eastern end of the Upper City circuit stands the King's Gate, named for the magnificent relief that once guarded its inner face.

The figure shows a striding warrior in a short kilt, helmeted, carrying a battle-axe and a long curved sword. He is heavily muscled, his hair tied back, his expression confident and serene.

Earlier scholars took him for a portrait of a king. Today most identify him as a god of war — perhaps the war-god Sharruma or another protective deity — guarding the royal city. The horns on the conical helmet are a divine attribute.

The original relief is in the Museum of Anatolian Civilizations in Ankara; an exact replica stands at the gate. The gate itself, like the Lion Gate, was a parabolic structure with massive jambs, and stood at the easternmost extension of the Upper City fortifications.

The Sphinx Gate and Yerkapı

The southernmost point of the city — its highest, most theatrical and most engineered — is Yerkapı, literally "the gate in the earth."

Here, instead of following the contour, the Hittite engineers built an enormous artificial pyramidal embankment, roughly 250 metres long and 30 metres high, faced with sloping stone slabs that still gleam white in the sun.

The embankment is one of the most remarkable feats of earth-and-stone engineering of the Bronze Age. Its outer face slopes upward at roughly 35 degrees and was originally smoothed and plastered, so that a besieger would have faced an unbroken, slippery, glittering white slope rising to the sky.

On top of this rampart ran a stretch of city wall, pierced by the Sphinx Gate, flanked by four monumental sphinxes carved from limestone.

The four sphinxes had complex histories:

• Two — the so-called Berlin and Istanbul sphinxes — were taken to Europe in the early 20th century for conservation;
• They were eventually repatriated to Türkiye, the Istanbul example after the First World War and the Berlin example after a long diplomatic campaign in 2011;
• All are now displayed in the Boğazkale Museum in the village below the site.

Beneath Yerkapı, cutting straight through the embankment, runs a 71-metre corbelled stone tunnel — the most spectacular postern at Hattusa.

Walking through it today, with the rough limestone walls leaning inward overhead and the daylight pouring in at both ends, is one of the unforgettable experiences of any visit to the site.

Its function is still debated:

• A sally port for surprise counter-attacks during a siege;
• A ceremonial passage for processions linking the city with the surrounding sacred landscape;
• A symbolic passage through the body of the great rampart, representing the king's mastery of the earth.

Most likely it served more than one purpose at once.

Visitors should not miss the climb to the top of the Yerkapı embankment, where the wall once stood. The view from the rim — across the entire Upper City and Lower City, with the Büyükkaya ridge in the distance — is the single best panorama of the site.

The Great City Walls and the Reconstructed Segment

The total length of the fortifications at Hattusa exceeds six kilometres.

They are built as casemate walls — two parallel curtain walls bonded by transverse partitions, with the cells between filled with rubble and topped by a fighting platform. The outer face was protected by a glacis of packed earth and stone, and the entire circuit was studded with rectangular towers at intervals of roughly 25 metres.

The walls follow the natural contours of the terrain, climbing over rock outcrops, dropping into gullies, and bending around the natural citadels of Büyükkale, Sarıkale and Yenicekale. In several places the bedrock has been cut back to receive the wall foundations.

Between 2003 and 2005, under the direction of Jürgen Seeher, a 65-metre stretch of wall on the south-eastern side of the Lower City was rebuilt using strictly Hittite techniques:

• Mudbrick made on site from local clay and chopped straw;
• Wooden tie-beams of poplar embedded in the masonry to absorb seismic shock;
• Stone foundations of large unworked blocks;
• Lime mortar for the upper courses.

The reconstruction has weathered well, and gives visitors something almost no other Bronze Age site offers — a chance to see the walls in something close to their original height and bulk. The reconstructed segment is also an experimental archaeology project in its own right, monitored each year for cracking, weathering and structural behaviour.

Büyükkale — The Royal Citadel

The natural rock outcrop of Büyükkale (literally "Great Castle") rises sharply at the eastern edge of the Lower City, a fortress within the fortress.

It was the royal acropolis of Hattusa: throne room, residence, archive, treasury and chapel of the Great Kings. Its position made it the heart of the political and religious life of the empire.

Excavations have revealed a complex of courtyards and halls, including:

• An enormous columned audience hall (Building D), where foreign ambassadors were received;
• The main archive complex (Building A and Building E), source of many of the tablets used to reconstruct Hittite history;
• Several magazine rooms for treasure and equipment;
• Small shrines to the royal protective deities;
• A double gateway controlling access from the Lower City.

It was in the archives of Büyükkale that Hugo Winckler in 1906 discovered the cuneiform tablets that proved this site was Hattusa. The two-storey buildings of his time, with their fine plaster floors and beautifully fitted ashlar, have since been partly conserved and presented for visitors.

The view from the citadel back across the Lower City to the Upper City temples is itself worth the climb.

The Upper City Temples

The southern half of Hattusa, the Upper City, was developed on a grand scale during the imperial period, particularly under Tudhaliya IV.

Surveys and excavations have so far identified the remains of more than thirty temples here, ranging from modest single-cella shrines to substantial complexes nearly as large as the Great Temple of the Lower City. The temples were laid out along a network of paved streets, with their porches and altars oriented to suit the cults housed within.

Together they form one of the largest sacred precincts of the ancient Near East. Whether all thirty were functioning simultaneously is debated; many seem to belong to a late religious reform under Tudhaliya IV, an attempt to unify the cults of the empire's diverse peoples — Hattic, Luwian, Hurrian, Syrian — within the capital.

The temples share a recognisable plan:

• A walled precinct with a single, controlled entrance;
• An interior courtyard onto which storerooms and the cult chamber open;
• A single cella (occasionally two) for the divine image;
• A discreet rear chamber for the priests.

Many of the temples were equipped with subterranean libation channels and water basins for ritual purification.

Nişantaş — The Rock Inscription

On a vertical rock face in the Upper City stands Nişantaş, a heavily eroded hieroglyphic Luwian inscription of eleven lines, the longest of its kind known.

It is generally attributed to Suppiluliuma II, the last Great King of Hatti, and may recount his deeds, including a naval campaign against Cyprus.

Although the text is now almost unreadable, its scale and placement — visible from the streets below — speak to the way the Hittite court used monumental rock-cut writing to project royal memory.

The neighbouring Südburg ("South Fortress") complex, excavated by Peter Neve, includes a fine rock-cut chamber with another, better-preserved hieroglyphic inscription of Suppiluliuma II, mentioning his conquest of cities in southern Anatolia. Together the two monuments form a kind of imperial memorial precinct.

Sarıkale

The inner citadel of the Upper City, Sarıkale ("yellow castle"), occupies a sharp rocky knoll rising above the temple quarter.

It seems to have served as a secondary residence, perhaps for members of the royal family or for high cult functionaries. A small palace, a courtyard and the remains of fortifications crown the rock.

The views from the summit, across the entire Upper City to Büyükkale and the Lower City beyond, are some of the finest at Hattusa, and the short climb is well worth the effort.

Yenicekale

A second rocky outcrop in the Upper City was crowned by Yenicekale, a sharply terraced fortress whose function is unclear.

Its enormous polygonal masonry, fitted without mortar to vertiginous heights, is one of the most striking pieces of Hittite engineering on the site. The terraces step up the natural rock in a way that recalls Inca masonry on the other side of the world; the resemblance is, of course, coincidental, but the engineering principles are similar.

The Postern Tunnels

In addition to Yerkapı, Hattusa was equipped with several smaller postern tunnels — discreet stone-built passages driven through the casemate walls to allow sorties, messengers and secret ingress and egress in time of siege.

Several can still be entered and walked through, providing the curious sensation of moving from the bright outer slope to the shadowed interior of a Bronze Age city in a few crouching steps.

The corbelled construction technique used in all the posterns — large flat slabs laid in successive overlapping courses to form a pointed arch — is a hallmark of Hittite military engineering, used here long before the true arch was developed in Roman architecture.

Other features worth seeking out

• The grain silos below the southern wall, where excavators found burnt remains of an enormous stockpile of cereal — enough, it has been calculated, to feed a city of tens of thousands for many months.
• The rock-cut reservoirs of the Upper City, part of an elaborate water-management system that included dams on the Budaközü.
• The Lion Basin, a stone basin carved with lion-head spouts, possibly used in a temple precinct.
• The Chamber 2 inscription at the Südburg complex — six lines of hieroglyphic Luwian by Suppiluliuma II, listing the cities he conquered in his last campaigns.

Hittite Religion and Daily Worship

To understand the monuments of Hattusa, it helps to know something of the religion they served.

The Hittites practised a polytheistic faith that they themselves called the religion of the "Thousand Gods of Hatti." This was not hyperbole: the royal pantheon really did include hundreds of named deities, drawn from every people the empire had absorbed.

The chief gods of the state cult were:

• Tarhunna / Teshub, the Storm God — chief male deity, patron of the king, lord of weather and war;
• The Sun Goddess of Arinna / Hepat — supreme goddess, "Queen of Heaven and Earth," patroness of the royal house;
• Sharruma, their son — divine protector of the king;
• Telipinu, the agricultural god whose disappearance caused famine;
• Kamrushepa, goddess of magic and healing;
• The Sun God of Heaven (a separate deity from the Sun Goddess of Arinna);
• The Moon God;
• Mountain gods, river gods, and the protective deities of cities, gates and even individual rooms.

Hittite religion was notably syncretic. As the empire absorbed new peoples, their gods were incorporated into the state pantheon. This openness was a deliberate political strategy: a Hurrian or Luwian subject who saw his own gods honoured at Hattusa was, in a sense, ritually included in the empire.

The king and queen were the chief priests of the realm. They were expected to perform an enormous calendar of festivals, processing in person from temple to temple, sacrificing, libating and singing hymns in a mixture of Hittite, Hurrian and Hattic. When campaigns took the king away from the capital, the festivals had to be postponed; the surviving ritual texts complain of the consequences.

Ordinary citizens had their own household shrines, set up in the corner of a courtyard or in a niche beside the hearth. Small clay figurines of gods, found by the thousands across the site, give a glimpse of this private piety.

Yazılıkaya — The Sanctuary of the Gods

Two kilometres east of the city walls, in a narrow cleft of limestone outcrops, lies Yazılıkaya — literally "inscribed rock."

It is the largest known open-air Hittite sanctuary, and the most complete pictorial witness to Hittite religion that has survived. No other Hittite site offers such an immediate, vivid encounter with the gods of the empire.

The setting

The sanctuary occupies a natural rock formation in which weathering has carved two narrow chambers, both open to the sky. A temple complex was built in front of the rock chambers, framing them with a courtyard, an entrance gate and a colonnaded portico. Today only the foundations of the temple buildings survive, but the rock chambers themselves are remarkably well preserved.

The rock surfaces were carefully prepared and polished before carving, and the figures were originally painted in red, blue, yellow and white — traces of pigment can still be detected in protected niches.

Chamber A — The Great Gallery

The larger of the two chambers, Chamber A, opens to the sky like a roofless gallery.

Two converging files of carved gods and goddesses approach a central scene in which:

• Teshub, the great storm god, stands on the shoulders of two mountain gods, holding a club;
• His consort Hepat, the Hurrian mother goddess, stands on a panther, approaching him;
• Behind Teshub follow male gods — bull-men, warrior gods, the patron deities of cities;
• Behind Hepat follow goddesses — moon goddess Ningal, the goddess of writing, the divine handmaids.

In total, more than 60 deities are depicted, each labelled with a Hurrian name in hieroglyphic Luwian script. Below the central scene stands the figure of the young god Sharruma, son of Teshub and Hepat, mounted on a panther.

The whole composition is sometimes called "the procession of the Thousand Gods of Hatti." It is the most complete visual representation of the Hittite-Hurrian pantheon to survive from antiquity.

Chamber B — The Private Chapel

Smaller, narrower and intensely atmospheric, Chamber B carries some of the most striking reliefs at the site.

• Along one wall, twelve gods of the underworld stride in single file, dressed in short kilts and conical helmets — the famous "procession of the twelve gods." Their identification is uncertain; they may be the twelve underworld deities mentioned in Hittite ritual texts.
• Opposite them, a vertical relief shows the strange Sword God (or "Dagger God"): a deity whose torso emerges from the pommel of a great inverted sword whose blade plunges into the bedrock. Two crouching lions flank his shoulders. This is one of the most unusual divine images of the ancient Near East.
• On a third wall, the god Sharruma embraces a king — almost certainly Tudhaliya IV — guiding him with one arm and holding his wrist with the other in a gesture of divine protection.

Chamber B is widely interpreted as a memorial chapel for Tudhaliya IV, perhaps designed to host the king's funerary cult.

Niches in the rock walls of Chamber B may once have held cult objects, perhaps ash containers or images of the deceased king.

The procession and its meaning

Modern scholars have long debated the purpose of the great gallery.

A persuasive recent interpretation, advanced by Jürgen Seeher and developed by Eberhard Zangger and Rita Gautschy, sees Chamber A as a kind of calendrical monument — a stone-carved map of the Hittite religious year, in which the gods' positions correspond to phases of the moon, the solar year and the festival cycle. On this reading, the sanctuary is at once a pantheon, a calendar, and a cosmic diagram.

Other scholars emphasise the dynastic dimension: the procession is, above all, a permanent witness to the religious legitimacy of the Hittite Great King, who appears in Chamber B in literal embrace with the god who validates his rule.

Both readings can be true at once. Yazılıkaya is the kind of monument that gathers meaning into itself like a magnet.

The Hurrian dimension

Although the rock was already a holy place in the Old Kingdom, the surviving reliefs were completed during the great religious reform of Tudhaliya IV in the second half of the 13th century BC.

They reflect the deeply Hurrian flavour of late Hittite court religion — the gods are largely Hurrian, the names are Hurrian, and the iconography draws on Syrian and Mesopotamian as well as Anatolian traditions.

This was not an accident. Tudhaliya IV's mother, Puduhepa, was a Hurrian priestess from Kizzuwatna, and as queen she actively promoted Hurrian religious traditions at court. Yazılıkaya is, in a sense, her theological monument as much as her son's.

Visiting Yazılıkaya today

To stand in Chamber A in the slanting light of a spring afternoon, surrounded by the silent procession of carved gods, is to come about as close as a modern visitor can come to the religious imagination of the Hittite court.

The two chambers are easily accessible by car from the main Hattusa site, by way of a 2-kilometre road. Walking is possible but adds significant time. The car park is small but adequate. The site is normally less crowded than the main city, and a quiet visit is usually possible.

The best light for photography in Chamber A is mid-morning, when the sun reaches into the gallery from the east. Chamber B is more difficult: its narrow shape and high walls keep most of the carvings in shadow, but late afternoon brings warm reflected light that helps reveal the relief.

Allow at least 45 minutes to an hour for a thorough visit; an hour and a half for a meditative one.

Some visitors find Yazılıkaya more moving than the city itself. The combination of the natural rock setting, the silence, and the sheer density of carved gods makes it one of the most evocative ancient places in the world.

The Boğazköy Archive

Among all the discoveries at Hattusa, the cuneiform archive is perhaps the most consequential for world history.

Over 30,000 clay tablets and fragments have been excavated from Büyükkale, the Great Temple and several Upper City buildings, beginning with Hugo Winckler's first season in 1906.

The languages of the archive

The tablets are written in at least six languages:

• Hittite (Nesite) — the language of the royal chancery, and the earliest attested Indo-European language;
• Akkadian — the diplomatic lingua franca of the Late Bronze Age, used in international correspondence;
• Hurrian — important for ritual and mythological texts;
• Hattic — the indigenous pre-Hittite language, preserved chiefly in liturgical formulae;
• Luwian — a closely related Indo-European language, well represented in religious texts and in the hieroglyphic inscriptions of the empire;
• Sumerian — used in scribal training and in scholarly compendia.

A few tablets even contain bilingual or trilingual versions of religious texts, used in scribal schools as exercises in translation.

What the tablets contain

The tablets cover an extraordinary range of genres. Among them:

International treaties with Egypt, Mitanni, Kizzuwatna, Amurru, Ugarit and other powers — including the Hittite copies of the Treaty of Kadesh. These are among the most important sources for the political history of the Late Bronze Age.

The Hittite Laws, a code of around 200 clauses regulating everything from inheritance and marriage to homicide, slavery and price-setting — a remarkably humane code by ancient standards, generally preferring compensation to corporal punishment. The Laws survive in multiple editions, showing how the code was revised over the centuries.

Royal annals, in which kings such as Mursili II describe their campaigns year by year. These are among the earliest substantial historical narratives in any Indo-European language.

State correspondence — letters between the Great King and his vassals, governors and foreign peers. The "Tawagalawa Letter," concerning a king of Ahhiyawa (possibly Mycenaean Greece), has been at the centre of decades of debate about Hittite contact with the Aegean world.

Oracle inquiries, in which scribes record the questions put to the gods through liver-divination, bird-omens and lot-casting. These are an invaluable window onto the daily anxieties of the royal court.

Ritual and festival texts, including the great spring festival (the AN.TAH.ŠUM) and the autumn festival (nuntarriyašha), which together occupied weeks of the royal calendar.

Hittite literature and myth — among them:

• The Anatolian recensions of the Epic of Gilgamesh, the oldest surviving translation of that great Mesopotamian poem;
• The Song of Kumarbi (and the rest of the so-called "Kingship in Heaven" cycle), in which the sky god Anu is overthrown by Kumarbi, who in turn is overthrown by Teshub — a story that has been compared in detail with Hesiod's Theogony and is often cited as evidence for Near Eastern influence on early Greek literature;
• The Myth of Telipinu (the disappearance and return of the agricultural god, with parallels to later "dying and rising god" stories);
• The Plague Prayers of Mursili II, which read almost like a personal diary of religious crisis.

Administrative and economic texts — inventories, ration lists, land grants — that allow detailed reconstruction of the Hittite economy.

Medical and magical texts including treatments for fevers, recipes for ritual purifications, and incantations against demons.

Decipherment

The archive's significance is hard to overstate.

The decipherment of Hittite by the Czech Assyriologist Bedřich Hrozný in 1915 — famously announced with the sentence "Now bread you will eat, water you will drink," which suddenly revealed the Indo-European character of the language — opened an entire civilisation, and an entire language family, to modern scholarship.

Since then, an international community of Hittitologists has produced grammars, dictionaries, text editions and translations, supported by institutions in Germany, Italy, Türkiye, the United States and elsewhere. The Chicago Hittite Dictionary project at the Oriental Institute remains a flagship of the field.

Memory of the World

In 2001, the Boğazköy archive was inscribed on UNESCO's Memory of the World register, complementing the site's World Heritage status. The two listings together make Hattusa one of the very few archaeological sites in the world recognised for both its monumental remains and its written legacy.

How the tablets were stored

Recent work has shown that the archive was kept with considerable care.

Tablets were stored on wooden shelves along the walls of dedicated rooms. Each tablet had a colophon identifying the text, the scribe, the version, and sometimes the date. Catalogue tablets — bibliographic lists of the documents held in a given room — have themselves been found, allowing modern archivists to reconstruct the original organisation of the archive.

The major archive rooms were:

• Buildings A, D and E on Büyükkale, holding diplomatic, administrative and historical texts;
• The Temple I complex in the Lower City, holding the ritual and festival texts;
• A House on the Slope in the Lower City, an apparent scribal training centre with many Akkadian and Sumerian lexical texts;
• Several Upper City temples with their own working archives.

When the city was abandoned around 1180 BC, many tablets were left in place — falling from their shelves as the buildings burned and collapsed, and being baked, often accidentally, by the very fire that destroyed the city. It is to this catastrophe that we owe their survival.

The Treaty of Kadesh

Of all the documents recovered from the Boğazköy archive, none is more famous than the Treaty of Kadesh, concluded in 1259 BC between Hattusili III of Hatti and Pharaoh Ramesses II of Egypt in the twenty-first year of Ramesses' reign.

Background

For most of the 14th and 13th centuries BC, the two empires had been locked in a struggle for control of Syria. The Battle of Kadesh in 1274 BC had been the high-water mark of the conflict — a colossal engagement that left neither side decisively victorious.

In the decades that followed, both empires faced new threats:

• The Hittites were increasingly worried about Assyria, which under Adad-nirari I and Shalmaneser I was expanding aggressively westward;
• The Egyptians were preoccupied with internal stability and with renewed pressure from Libya and the early waves of the Sea Peoples.

Peace served everyone's interests.

The terms

The treaty has the form, and the language, of a sophisticated piece of international law. It establishes:

• A permanent peace between the two empires, "for ever and ever";
• A mutual defensive alliance against external attack and internal rebellion;
• The return of fugitives between the two kingdoms, with humane clauses against punishing those returned;
• Guarantees of dynastic succession — each ruler pledges to support the other's chosen heir, particularly against any usurper;
• A long list of divine witnesses from both pantheons, summoned to enforce the oath: a thousand gods and goddesses of Hatti and a thousand of Egypt.

The treaty is not, technically, a peace treaty alone; it is also a parity treaty and a mutual defence pact. Both kings are styled "Great King," addressing one another as brothers and equals. This was a major diplomatic concession on both sides.

The physical documents

The original was inscribed on a silver tablet, of which:

• The Egyptian version was copied in stone on the walls of the Karnak temple and the Ramesseum at Thebes;
• The Hittite version survived as cuneiform clay copies in the Büyükkale archive at Hattusa.

It is the only treaty of the Bronze Age for which we possess both sides' versions. The two texts differ in small but revealing details — each king, naturally, presenting himself as the magnanimous initiator of peace — but the substantive terms match.

The UN replica

A modern enlarged replica of the Hittite tablet was presented by Türkiye to the United Nations in New York. It hangs in the corridor outside the Security Council chamber as a symbol of the long tradition of international diplomacy.

Why it still matters

In every reasonable sense, the Treaty of Kadesh is the oldest international peace treaty in human history for which we have the text of both sides.

That such a document was negotiated, signed, archived in two languages on three continents, and partly honoured for the rest of the 13th century BC, is itself an extraordinary testament to the political maturity of the powers that ruled the Late Bronze Age — and to the city of Hattusa, where one half of the treaty was kept.

The treaty also bears witness to a moment of true cosmopolitan exchange. The Egyptian princess Maathorneferure, daughter of Ramesses II, was later sent to Hattusa as part of the diplomatic settlement and married Hattusili III; her dowry and her escort travelled the length of the eastern Mediterranean. A second Egyptian princess followed. These marriages were not love-matches but they cemented the peace, and they brought Egyptian craftsmen, scribes and luxury goods into the heart of Anatolia.

The wider diplomatic correspondence that accompanied the treaty — preserved at Hattusa as the so-called "Ramesses Letters" — is itself a precious witness to ancient diplomacy: letters of condolence, congratulations, gift-exchange, and gentle complaints about the slowness of imperial mail.

Puduhepa, queen and diplomat

Hattusili III's wife, Queen Puduhepa, deserves special mention. A Hurrian priestess from Kizzuwatna in south-eastern Anatolia, she became one of the most powerful queens of the Bronze Age.

She corresponded directly with Ramesses II — her seal appears alongside her husband's on diplomatic letters — and she conducted the marriage negotiations that brought Maathorneferure to Hattusa. She was also a religious reformer in her own right, sponsoring the systematic Hurrianisation of Hittite cult practice that culminated in the iconography of Yazılıkaya.

Few queens of the Bronze Age are as fully attested in the written record. Her prayers, her vows, her correspondence and her cylinder-seal impressions together give us a portrait of a major political figure in her own right.

Archaeological Work

Hattusa has been the subject of continuous scholarly attention for nearly two centuries, and the archaeological history of the site is itself a story worth telling.

Charles Texier (1834)

The French architect and traveller Charles Texier, sent to Anatolia to study Roman remains, stumbled in 1834 onto the colossal ruins above the village of Boğazköy.

He drew the Lion Gate and the Yazılıkaya reliefs in superb plates that astonished European audiences. Texier guessed the ruins were Roman, then Median; he had no idea he was looking at the capital of a forgotten empire. His three-volume Description de l'Asie Mineure (1839–1849) brought Hattusa to the attention of European scholars for the first time.

William Hamilton and others (1830s–1880s)

Texier was followed by a steady trickle of European travellers, including the British geologist William Hamilton, who confirmed and supplemented Texier's descriptions, and the German classical scholar Heinrich Barth.

By the late 19th century, scholars had begun to suspect, on the basis of references in Egyptian and Assyrian sources, that a great kingdom called "Hatti" had once existed in central Anatolia. The puzzle of where its capital had been remained unsolved.

Ernst Chantre (1893–1894)

The French archaeologist Ernst Chantre conducted the first modest soundings at the site in the 1890s.

He found cuneiform tablets — the first ever recovered from Boğazköy — but in a language no one could yet read. The tablets were sent to Paris; their decipherment would have to wait two decades.

Hugo Winckler and Theodor Makridi (1906–1912)

Everything changed in 1906.

The German Assyriologist Hugo Winckler, working in cooperation with Theodor Makridi of the Imperial Ottoman Museum in Istanbul, began excavating Büyükkale. Within weeks they had unearthed thousands of cuneiform tablets, and Winckler — a specialist in Akkadian — recognised among them the Hittite version of the famous treaty already known from the walls of Karnak.

The lost capital of the Hittites had been found.

Winckler's seasons between 1906 and 1912 yielded more than 10,000 tablets, the spectacular reliefs of the King's Gate and the Sphinx Gate, and the basic outline of the city plan. Working conditions were difficult — the tablets were stored in tents, conserved with primitive methods, and shipped in batches to Berlin and Istanbul — but the scientific impact was extraordinary.

The interwar pause and Kurt Bittel (1931–1977)

After the disruption of the First World War and the Ottoman collapse, sustained excavation resumed in 1931 under the German Archaeological Institute (Deutsches Archäologisches Institut, DAI).

The new director, Kurt Bittel, would dominate Hittite archaeology for the next four decades. Bittel:

• Produced the first scientific maps of the site;
• Excavated the Great Temple in the Lower City;
• Defined the chronology of Hittite ceramics still in use today;
• Trained a generation of archaeologists, both German and Turkish;
• Produced the foundational monograph Die Hethiter, which remains a classic.

Bittel's work was briefly interrupted by the Second World War but resumed quickly afterwards. By the time he retired in 1977, the broad outlines of Hattusa's archaeology had been firmly established.

Peter Neve (1978–1994)

Bittel's successor, Peter Neve, shifted the focus to the Upper City.

He uncovered most of the more than thirty temples now known, the pools and reservoirs, and the great Südburg sacred complex with its Luwian inscription of Suppiluliuma II. He also conducted the first systematic excavation of Yenicekale and Sarıkale.

Neve's work transformed the understanding of Hittite religious architecture and demonstrated the enormous scale of the imperial-period sacred precinct.

Jürgen Seeher (1994–2005)

Under Jürgen Seeher, work concentrated on Bronze Age urbanism — the houses of the Lower City, the grain silos at the southern slope (with their tens of thousands of carbonised cereal kernels), the great rock-cut reservoirs of the Upper City and, above all, the experimental reconstruction of 65 metres of city wall using authentic mudbrick techniques.

Seeher's popular guidebook to Hattusa remains one of the best introductions to the site in any language. His tenure also saw a major expansion of conservation work and a programme of stabilisation of the standing monuments.

Andreas Schachner (2006–present)

The current director, Andreas Schachner, has expanded the research programme in several directions:

• Regional survey of the territory around Hattusa, mapping the network of secondary sites that supported the capital;
• Geomagnetic prospection of unexcavated quarters, allowing whole districts to be planned without digging;
• Conservation of the standing monuments, with particular attention to the reconstructed wall, the Yerkapı tunnel and Yazılıkaya;
• A comprehensive re-evaluation of the chronology of the Late Bronze Age destruction, drawing on tree-ring dating and radiocarbon evidence;
• New work on the water-management system, including previously unknown dams and channels.

Excavation continues every summer, and major new discoveries — including evidence of monumental water management and previously unknown sanctuaries — are still being announced. The DAI excavation house at Boğazkale is one of the longest-running archaeological projects in the world.

Museums

Two museums are essential complements to a visit:

The Boğazkale Museum, in the village immediately below the site, displays finds from Hattusa and Yazılıkaya, including:

• The repatriated Sphinx of Yerkapı, returned from Berlin in 2011;
• Cuneiform tablets and bullae;
• Bronze figurines, pottery, seals and weapons;
• A careful presentation of the site's archaeological history with photographs of the excavators.

It is small but unusually well curated, and the displays are in Turkish and English.

The Çorum Museum in the provincial capital holds one of the largest and most important Hittite collections in the world, with a magnificent display of:

• Cult objects from Hattusa and Alacahöyük;
• Hittite weapons and ceremonial axes;
• A large selection of cuneiform tablets and seals;
• Ivories and luxury goods showing the cosmopolitan character of imperial Hatti;
• Important material from Şapinuwa (Ortaköy) and Eskiyapar, the two other great Hittite centres of Çorum province.

The crown jewels of Hittite art — the original King's Gate warrior, the original Sphinx Gate sphinxes that were not in Berlin, the Treaty of Kadesh tablet and many others — are held in the Museum of Anatolian Civilizations in Ankara, generally considered one of the finest archaeological museums in the world.

Numbers and Measurements

Visitor Information

Getting There

Almost everyone arrives by car.

From Ankara: Take the E88/D200 highway east toward Samsun for about 170 kilometres to Sungurlu, then turn south and follow the well-signposted Boğazkale road for 30 kilometres. The total drive is around 200 kilometres, or 2.5–3 hours in normal traffic.

From Çorum: the trip is shorter — about 80 kilometres, or 1.5 hours, via Alacahöyük. This is the most rewarding route for archaeology enthusiasts, since it allows a stop at Alacahöyük on the way.

From Istanbul: count on a long day's drive (about 7 hours via Ankara) or, better, an overnight in Ankara and a fresh start the next morning.

By bus: long-distance buses serve Sungurlu several times a day from Ankara, Istanbul and Samsun, and local minibuses (dolmuş) connect Sungurlu to Boğazkale, though they are infrequent and inconvenient for a day trip. For most travellers, a private car or a guided tour is the only practical option.

Guided tours: day-trip and overnight tours from Ankara and Cappadocia are widely available, often combining Hattusa with Alacahöyük and the Çorum Museum.

Hours, Tickets and the Museum Pass

The site is open daily, generally from 08:30 to 19:00 in the summer season (April–October) and 08:30 to 17:00 in winter, but hours can change; check the Ministry of Culture website before travelling.

A single ticket covers both Hattusa and Yazılıkaya, and is purchased at the main gate of the archaeological site.

The Müzekart+ (Turkish Museum Pass) and the Museum Pass Türkiye (the foreign-visitor version) are both accepted and are excellent value if you are also visiting Çorum Museum, Alacahöyük and/or the Museum of Anatolian Civilizations in Ankara on the same trip.

How Much Time

Plan on a minimum of three hours for the main Hattusa loop and another hour for Yazılıkaya. That is a brisk schedule with limited stops.

A leisurely visit, with time for photography and the museum in Boğazkale, takes most of a day. Serious enthusiasts often spend a second day exploring the Upper City temples and the nearby site of Alacahöyük.

A Vehicle is Strongly Recommended

The internal circuit of Hattusa is roughly 6 kilometres long, on a road that climbs steeply from the Lower City to Yerkapı and loops back past the Upper City monuments.

There is no shuttle service. Walking the full loop in summer heat is exhausting; most visitors drive between the major stops and walk the short paths in between.

Renting a bicycle in the village is a charming alternative in spring and autumn — the road is in good condition and traffic inside the site is minimal.

Season

The best months are late April to mid-June and mid-September to late October.

July and August are very hot, with little shade; bring more water than you think you need.

November to March can be magical when the ruins are dusted with snow, but the road from Sungurlu can close in bad weather, and the smaller monuments may be inaccessible. The Boğazkale Museum stays open year-round.

The Boğazkale Museum

Immediately below the Lower City, the Boğazkale Museum is a small but essential stop.

Its highlights include:

• One of the repatriated Yerkapı sphinxes, returned from Berlin in 2011;
• Fine cuneiform tablets and bullae;
• Hittite seals, bronzes and pottery;
• A careful presentation of the site's archaeological history with photographs of the excavators.

Allow 45 minutes to an hour. The museum is closed on Mondays in some seasons; check before visiting.

The Çorum Museum

If your route allows it, do not miss the Çorum Archaeological Museum in the provincial capital, 80 km north.

Its Hittite galleries are among the richest in Türkiye, and the explanatory panels in Turkish and English are excellent. Highlights include the Şapinuwa tablets, royal seals, and a superb collection of Hittite cult objects.

Allow 2 hours for a thorough visit.

Alacahöyük

About 25 kilometres north-west of Hattusa lies Alacahöyük, one of the most important pre-Hittite and Hittite sites in Anatolia.

Its highlights include:

• The famous Sphinx Gate, with its own pair of monumental sphinxes;
• The royal tombs of the Early Bronze Age that produced the celebrated standards of Alacahöyük (now the emblem of the city of Ankara);
• A small but excellent on-site museum;
• A 13th-century BC Hittite temple precinct.

Many guided tours combine Hattusa and Alacahöyük in a single day; this is highly recommended.

Accessibility

The terrain at Hattusa is steep, rocky and uneven.

• The main monuments — the Lion Gate, the Sphinx Gate, Yerkapı, the Great Temple — can be viewed from the road, but full appreciation of any of them requires walking on rough paths and steps.
• The Yerkapı tunnel involves a low, sloping passage with uneven footing; visitors with mobility issues should view it from outside.
• Yazılıkaya is more accessible: a short, mostly level path leads from the car park to both chambers.
• Visitors with limited mobility can still enjoy much of the site by car, with stops at the principal monuments and views from the road.

Practical tips

• Bring more water than you think you need; there is no reliable source within the site.
• Sun protection is essential from May onwards: hat, sunscreen, sunglasses.
• Wear sturdy walking shoes; the paths include loose stones, steps and bedrock.
• A light jacket is wise even in summer, since the wind on the upper ramparts can be fierce.
• A printed map or guidebook is very helpful; signage is good but not exhaustive.
• The Seeher guidebook, available at the site, is the best on-site companion in English.

Combining Hattusa with other Hittite sites

A serious Hittite itinerary might include, over three or four days:

• Hattusa + Yazılıkaya + Alacahöyük + Boğazkale Museum + Çorum Museum (two days, based in Boğazkale or Çorum);
• A side-trip to Şapinuwa (Ortaköy), a second Hittite capital recently being excavated;
• A return via Ankara to visit the Museum of Anatolian Civilizations, with its unmatched display of original Hittite art and the Treaty of Kadesh tablet.

A suggested half-day route

For travellers with only an afternoon, the following order works well:

1. Start at the Lower City Great Temple (Temple I). Allow 30 minutes to walk through the temple precinct and admire the green stone.
2. Drive up to the Lion Gate. Five minutes by car. Spend 15 minutes here, including time for photographs of both lions.
3. Continue to Yerkapı and the Sphinx Gate. Climb the steps to the top of the embankment for the panoramic view. Walk through the 71-metre tunnel and back up the steps on the other side. Allow 30 minutes.
4. Drive on to the King's Gate. Ten minutes. Admire the warrior relief replica; spend 10 minutes.
5. Pause briefly at the Nişantaş inscription and the Südburg complex. A short loop on foot from the road. Allow 15 minutes.
6. End at Büyükkale. A short, steep climb gives spectacular views back over the Lower City. Allow 30 minutes.
7. Drive 2 km east to Yazılıkaya. Half a day's culmination. Allow 45 minutes to an hour.

Total: about 3.5 hours of structured visiting. Add the Boğazkale Museum for a satisfying half-day.

A suggested full-day route

For a more relaxed visit, repeat the above schedule with longer pauses, add a picnic lunch somewhere quiet on the Upper City road, include a walking detour to Yenicekale and Sarıkale, and finish with the Boğazkale Museum in the late afternoon.

Where to stay

The village of Boğazkale has a handful of small family-run hotels and guesthouses, several of them very welcoming. Rooms are simple, prices are modest, and breakfast on a terrace overlooking the ancient city is one of the small pleasures of an archaeological journey.

For travellers who prefer more conventional accommodation, Çorum (80 km north) and Sungurlu (30 km north) both have business hotels with air conditioning and full restaurants. Some visitors base themselves in Cappadocia (about 250 km south) and treat Hattusa as a long day-trip; this is feasible but tiring.

Where to eat

Family restaurants in Boğazkale serve excellent home cooking — typically grilled lamb, vegetable stews, fresh bread baked in a wood oven and the famous Çorum leblebi (roasted chickpeas) for dessert.

In Çorum, look for the local speciality Çorum mantı — small ravioli filled with spiced lamb and served with garlic yoghurt — and for İskilip dolması, a steamed rice-and-lamb dish from the nearby İskilip district.

The whole region is also famous for its honey, its walnuts and its fruit preserves — pick up jars and packets in the village shops as souvenirs that are as edible as they are evocative.

Frequently Asked Questions

What is Hattusa, in a sentence? Hattusa was the capital, for about half a millennium, of the Hittite Empire — one of the four great powers of the Late Bronze Age, alongside Egypt, Assyria and Babylon — and is today a UNESCO World Heritage Site in central Türkiye.

Where exactly is the site? Near the village of Boğazkale, in Çorum Province, about 200 km east of Ankara and 80 km south-west of Çorum.

When was the Hittite Empire? Roughly 1650 to 1180 BC, with Hattusa serving as the capital throughout, apart from a brief interlude when Muwatalli II moved the court to Tarhuntassa in the early 13th century BC.

Who first identified the site as Hattusa? The German Assyriologist Hugo Winckler, working with Theodor Makridi of the Ottoman Imperial Museum, identified the site through the cuneiform tablets they excavated on Büyükkale in 1906.

What is the Treaty of Kadesh, and why is it famous? It is a peace treaty concluded in 1259 BC between the Hittite Great King Hattusili III and Pharaoh Ramesses II of Egypt, after the Battle of Kadesh of 1274 BC. Surviving in both Hittite cuneiform and Egyptian hieroglyphic versions, it is the oldest international peace treaty for which we have the texts of both parties. A replica hangs in the United Nations headquarters in New York.

What is Yazılıkaya? A natural rock sanctuary 2 km east of Hattusa, with two open-air chambers covered in monumental reliefs of more than 60 Hittite-Hurrian gods. Its present form was completed under Tudhaliya IV in the late 13th century BC.

What language did the Hittites speak? Hittite — an Indo-European language closely related to Luwian and Palaic, and the earliest Indo-European language preserved in writing.

How many cuneiform tablets have been found? More than 30,000 tablets and fragments, in six languages. The archive is on the UNESCO Memory of the World register.

Why did Hattusa fall? Around 1180 BC the city was burned and abandoned, almost certainly as a result of a combination of pressures: the migrations of the Sea Peoples, prolonged drought and famine, the breakdown of long-distance Bronze Age trade, and possibly internal dynastic conflict. Recent evidence suggests the court may have evacuated the city before the final destruction.

Is the site suitable for children? Yes — older children especially love the Yerkapı tunnel, the Lion Gate and the spookier corners of Yazılıkaya. Younger children will need plenty of water, sun protection and good walking shoes.

How long should I stay? A minimum of half a day for Hattusa and Yazılıkaya. A full day allows a more leisurely pace, including the Boğazkale Museum. Two days, with Alacahöyük and the Çorum Museum, make a proper Hittite itinerary.

Can I see the original of the King's Gate relief or the Treaty of Kadesh? Both are in the Museum of Anatolian Civilizations in Ankara. Excellent replicas stand at the site itself, and the Boğazkale Museum has the Yerkapı sphinx.

Is photography allowed? Yes, throughout the site and at Yazılıkaya. Flash is not permitted in the rock chambers in order to protect the surviving pigment traces. Drone use requires advance permission.

What's the difference between Hittites and Hatti? The Hatti were the indigenous, non-Indo-European inhabitants of central Anatolia who lived at the site before the arrival of the Indo-European-speaking newcomers. The Hittites are the modern name for those newcomers, who absorbed Hattic culture, kept the place-name "Hattusa" and called their land "the Land of Hatti." In their own language, they called themselves Neša, after their earlier capital Kanesh/Nesa.

Why do we use the term "Hittite" if they called themselves something else? The term "Hittite" reaches modern scholarship through the Hebrew Bible, which mentions a people called the Hittim among the inhabitants of Canaan. When 19th-century scholars realised that this biblical name and the Hatti of Egyptian and Assyrian sources referred to the same people, the convention was set. Most modern Hittitologists would prefer "Nesite" — the people's self-designation — but the older term has stuck.

Was iron really invented at Hattusa? Iron-smelting was practised at Hattusa earlier than in many parts of the ancient world, and a famous letter of Hattusili III to a Mesopotamian king politely refuses an urgent request for an iron dagger on the grounds that "good iron" is hard to come by. Iron was rare and prized in the Hittite period; it became the dominant metal only after the empire's fall, in the so-called Iron Age that began around 1200 BC. So while Hattusa was not literally the "birthplace of iron," it played an important role in the early history of iron metallurgy.

Are there any other unmissable Hittite sites within reach? Alacahöyük (25 km, essential), Şapinuwa / Ortaköy (60 km, active excavation), Eskiyapar (20 km), and the rock reliefs at Fasıllar and İvriz further afield. The Black Sea archaeological circuit also includes Samuha and Nerik, both important cult cities of the empire.

Is there a connection to Troy? Hittite diplomatic texts mention a city called Wilusa in western Anatolia, almost certainly to be identified with Troy/Ilion. The "Tawagalawa Letter" and the "Manapa-Tarhunta Letter" both discuss diplomatic and military exchanges in the region. The relationship between Wilusa and the Homeric tradition is one of the most fertile debates in modern scholarship — and Hattusa's archive is at the heart of it.
