Hattuşa

i.The Site on the High Plateau

Hattuşa (also Hattusha or Hattusas; the cuneiform Ḫattuša) lies at the northern edge of the central Anatolian plateau, at an elevation of approximately one thousand metres, in the modern district of Boğazkale in Çorum province. The site occupies a steeply sloping triangle of land between two stream valleys, with the long ridge of the citadel — Büyükkale, "the Great Castle" — at its highest northeastern point and the great fortified circuit of walls running down the slopes around it. From the citadel, the view across the surrounding country to the wider Anatolian plateau is one of the great archaeological views in the world: in a single sweep, the eye takes in nearly all of what was once the heart of the Bronze Age Hittite empire.

The settlement was already substantial by the early second millennium BCE, when the small village on the Boğazkale heights was an Assyrian trade-colony-period (kārum-period) settlement, attested in the cuneiform business archives of the contemporary Kanesh / Kültepe trading hub near modern Kayseri. The Hittite-period transformation of Hattuşa into an imperial capital came around 1650 BCE under king Hattusili I, who chose the defensible plateau site for his new capital and named the city after the surrounding country (Hatti).

The "City of a Thousand Gods" — Bronze Age capital of the great Indo-European Hittite empire, whose treaty with Ramesses II is the first known international peace agreement in human history.

ii.The Hittite Old Kingdom and Empire (c. 1700–1180 BCE)

The Hittites — known to themselves as the people of Nesili, "those who speak Nesite" (the language modern scholars call Hittite) — established their first written records around 1650 BCE, under king Hattusili I and his successor Mursili I (who sacked Babylon in c. 1595 BCE, the moment that brought down the Old Babylonian state). The early phase of Hittite rule — known as the Old Kingdom — lasted into the late 15th century BCE, with Hattuşa as the political and religious capital throughout.

The defining transition came around 1380 BCE with the accession of Suppiluliuma I (reigned c. 1344–1322 BCE), the founder of the Hittite Empire. Under Suppiluliuma I and his successors — Mursili II, Muwatalli II, Hattusili III, and Tudhaliya IV — the Hittite state became one of the great powers of the late Bronze Age, ruling territory from the Aegean coast of western Anatolia eastward to the Euphrates and southward into northern Syria. The empire's principal rivals were the New Kingdom of Egypt (under Akhenaten, Tutankhamun, Seti I, and Ramesses II), the kingdom of Mitanni in upper Mesopotamia, and the rising kingdom of Assyria.

The single best-known historical event of the Hittite Empire is the Battle of Kadesh in approximately 1274 BCE, fought between Muwatalli II of Hatti and Ramesses II of Egypt at the Syrian city of Kadesh on the Orontes. The battle was tactically inconclusive but strategically a Hittite success. Sixteen years later, in approximately 1259 BCE, Hattusili III and Ramesses II concluded the Treaty of Kadesh — the first known international peace treaty in human history, surviving today in both Hittite (cuneiform) and Egyptian (hieroglyphic) versions. A copy of the Hittite-language tablet is preserved in the Istanbul Archaeological Museum; the Egyptian version is inscribed on the walls of the Karnak temple at Luxor. The United Nations holds an enlarged replica of the treaty on the wall outside the Security Council chamber in New York — the first international peace agreement.

The empire collapsed around 1180 BCE, in the broader Late Bronze Age collapse that brought down most of the great powers of the eastern Mediterranean. The collapse was likely a combination of drought, famine, internal political fragmentation, and external pressure from the so-called "Sea Peoples." Hattuşa itself was burnt and abandoned. The last king on the throne, Suppiluliuma II (reigned c. 1207–1178 BCE), oversaw what appears to have been an orderly evacuation of the capital before its destruction — the great Hieroglyphic Luwian inscription in Chamber 2 of the Südburg complex is his memorial. The Hittite state never recovered.

iii.The Walls and the Four Gates

The Hittite Empire-period walls of Hattuşa — substantially the work of the 13th century BCE — form a great fortified circuit of approximately six kilometres running around the entire settled area. The walls were built on a double-line system: an inner main wall topped with mud-brick crenellations and great rectangular towers, and an outer lower wall (the proteichisma) providing the first line of defence. The construction technique combined a foundation course of cyclopean limestone blocks with mud-brick superstructure, partly preserved at the great Yerkapı embankment in the south.

The wall circuit is punctuated by four monumental named gates, each of architectural and sculptural significance:

• The King's Gate (Kral Kapısı) — at the southeastern end of the wall circuit, with a famous relief slab depicting a warrior figure (originally identified as a king, now generally interpreted as a warrior god, possibly the deity Sharruma). The relief is one of the most iconic surviving images of Hittite art.
• The Lion Gate (Aslanlı Kapı) — at the southwestern corner, with massive carved lions flanking the gateway as apotropaic guardians. The lions are deeply weathered but still in situ.
• The Sphinx Gate (Sfenksli Kapı) — at the highest southern point, with carved sphinx figures (the originals now in the Boğazkale Museum and the Istanbul Archaeological Museum; replicas at the site) that show the distinctive Hittite-Hurrian iconographic blend.
• Yerkapı ("Earth Gate") — the most spectacular surviving construction, a sloping artificial embankment seventy metres high running across the southern wall, with a long tunnel beneath it (the postern tunnel) running through the embankment from one side to the other. The tunnel still functions and can be walked through today.

The combined effect of the walls — with their double-line construction, the massive carved gates, the artificial Yerkapı embankment, and the citadel of Büyükkale rising above — made Hattuşa one of the most heavily fortified cities in the late Bronze Age world.

iv.Büyükkale, the Temples, and the City of a Thousand Gods

The royal palace and administrative complex of Hattuşa stood on the high ridge of Büyükkale, at the northeastern end of the walled circuit. The palace complex included the royal residence, the throne room, the great halls of audience, and — most importantly — the royal archives, where the famous cuneiform tablets were stored on shelves in dedicated archive chambers. The palace foundations and the broad outline of the royal complex are visible today in plan.

The city was also the religious centre of the Hittite world, and the Hittites called their pantheon — with the formal grandiosity of their international treaties — the "Thousand Gods of Hatti" (the phrase appears throughout the Hittite treaty texts, invoking the gods of both contracting parties as witnesses to the agreement). The principal Hittite deities were the Storm God Tarhunt (often called by the Hurrian form Teshub in later texts) and the Sun Goddess of Arinna, the chief solar deity whose cult centre lay at the nearby (still-unidentified) site of Arinna. The great Temple I of Hattuşa — the Storm God's temple — stands in the lower city below Büyükkale, with massive limestone foundations and an extensive surrounding complex of storerooms in which substantial quantities of tablets were recovered.

Two kilometres north-east of the main city, the open-air shrine of Yazılıkaya (Turkish for "inscribed rock") preserves a stunning gallery of Hittite reliefs cut directly into the natural limestone rock faces. The main chamber (Chamber A) shows two parallel processions of male and female deities meeting at a central panel — the most complete surviving image of the Hittite-Hurrian pantheon. The smaller adjacent Chamber B preserves the famous twelve-deity relief and the relief of Tudhaliya IV being embraced by his patron deity Sharruma. The Yazılıkaya complex was the principal extramural cult site of Hattuşa.

v.The Cuneiform Archives — Memory of the World

The single greatest contribution of Hattuşa to world historical knowledge is the recovery of the Boğazköy Tablets — the great cuneiform archive of the Hittite imperial state. Approximately 30,000 clay tablets and fragments have been recovered from the site since the first major excavations of 1906–1908, with substantial additional material recovered in every subsequent campaign. The tablets cover the entire scope of Hittite imperial administration: international treaties (including the Treaty of Kadesh), royal correspondence, legal codes (the great Hittite law code, the most extensive surviving Bronze Age legal corpus outside the Old Babylonian Code of Hammurabi), religious-ritual texts, mythological narratives, historical annals, and the great prayer-and-omen literature of the Hittite religious tradition.

The Hittite language itself, recorded on the tablets, was identified as Indo-European by the Czech Assyriologist Bedřich Hrozný in 1915 — a landmark moment in linguistic history. Hittite is now recognised as the earliest documented Indo-European language, with attested texts predating the earliest Greek (Mycenaean Linear B), Sanskrit, and Latin sources by several centuries. The recognition of Hittite as Indo-European pushed the documented history of the Indo-European language family back by nearly a millennium and demonstrated that an Indo-European-speaking population had reached Anatolia by at least 2000 BCE.

UNESCO inscribed the Boğazköy Archive on the Memory of the World Register in 2001, recognising the archive as one of the most important documentary heritages in human history.

vi.From Texier (1834) to the Modern Excavations

The site of Hattuşa was unknown to Western scholarship until the French traveller-explorer Charles Texier visited the ruins on 28 July 1834, recognised their importance, and published a detailed account in his Description de l'Asie Mineure (1839–1849). Texier identified the city only tentatively (he guessed it was the Greek city of Tavium, mentioned by Strabo); the Hittite identification would have to wait for the decipherment of cuneiform later in the 19th century. Successive 19th-century travellers — Hamilton, Perrot, Humann — visited and recorded the site.

The first systematic excavations were conducted in 1906 by Hugo Winckler for the Deutsche Orient-Gesellschaft (German Oriental Society), with Theodor Makridi Bey as Ottoman co-director. Winckler's excavations in the first season uncovered the great royal archives — the most important single discovery in Hittitological history. Excavations were interrupted by the First World War and the early Republic, resumed under Kurt Bittel for the German Archaeological Institute in 1931, and have continued (with various interruptions) under successive German directors — Peter Neve, Jürgen Seeher, Andreas Schachner — to the present day. The Boğazkale site has been continuously excavated by the German Archaeological Institute for almost a century, making it one of the most exhaustively investigated archaeological sites in Türkiye.

vii.UNESCO Inscription and the National Park

Hattuşa was inscribed on the UNESCO World Heritage List in 1986 under the title "Hattusha: the Hittite Capital", recognising the site's outstanding universal value as one of the great Bronze Age imperial centres. The wider archaeological landscape was protected by the establishment in 1988 of the Boğazköy-Alacahöyük Historical National Park (Boğazköy-Alacahöyük Tarihi Millî Parkı), which combines the Hattuşa main site, the Yazılıkaya rock sanctuary, the adjacent Boğazkale Museum, and the second-major Hittite site of Alacahöyük twenty-five kilometres to the north.

Alacahöyük — although smaller than Hattuşa — has its own remarkable monuments: the Royal Tombs of the Early Bronze Age (c. 2300–2100 BCE), with their famous bronze and gold "sun discs" and bull/stag standards (now in the Museum of Anatolian Civilisations in Ankara); the Sphinx Gate, with its monumental sphinx figures and the famous "King and Queen offering to the bull" relief; and the Hittite-period temple complex. The Alacahöyük finds anchor the early sections of the Anadolu Medeniyetleri Müzesi (Ankara Museum) and are among the most important Early Bronze Age objects in the eastern Mediterranean.

viii.The Hittites in the Long Anatolian Story

The Hittite collapse around 1180 BCE marks one of the great inflection points in Anatolian history. With Hattuşa abandoned and the imperial state ended, Anatolia entered the so-called "Dark Age" of approximately four hundred years — a period of substantial population dislocation, the disappearance of writing, and the fragmentation of political authority. The Hittite legacy survived in two forms: in the Neo-Hittite city-states of southeastern Anatolia and northern Syria (Kummuh, Sam'al, Carchemish, Que/Hiyawa — see the Adıyaman essay on Kommagene as the descendant of Kummuh), and in the diffuse cultural memory that filtered into the later Phrygian, Lydian, and Iron Age Anatolian successor states.

For the modern study of antiquity, the Hittite recovery is one of the great archaeological achievements of the late 19th and 20th centuries. From having been a people known only through occasional biblical and Egyptian references (the "Hittites" of the Old Testament; the "Hatti" of Egyptian military records), they have been recovered as one of the three great powers of the late Bronze Age eastern Mediterranean, alongside Egypt and Babylon. The recovery has comprehensively rewritten the historical geography, linguistic history, and political map of the Bronze Age world.

ix.Visiting Hattuşa Today

Hattuşa is reached from Ankara (three hours by road, due east), Çorum city (an hour and a half north-east), or by long-distance bus to Sungurlu (the nearest town with regular bus service, with a half-hour onward taxi to Boğazkale). The site is open daily; the principal visit requires a full half-day on foot — the site is large, the walking is partly uphill, and the great features are spread across roughly five kilometres of the ancient circuit.

The standard itinerary moves from the entry car park up through the lower city (the great Temple I of the Storm God), along the eastern wall past Büyükkale to the King's Gate, then south to the Sphinx Gate and the Yerkapı tunnel, then west to the Lion Gate, and back down through the citadel area to the entry. A separate two-kilometre walk leads to the Yazılıkaya rock sanctuary, which should not be missed. The Boğazkale Museum at the site entrance houses the originals of the most important sphinx and other finds and is essential context for the visit.

Beyond Hattuşa itself, the wider Boğazköy-Alacahöyük National Park includes the Alacahöyük site twenty-five kilometres to the north, with its Early Bronze Age royal tombs and the Hittite sphinx gate. Travellers with more time should add a visit to the Anadolu Medeniyetleri Müzesi in Ankara — the principal national archaeological museum, which houses the most important moveable finds from Hattuşa, Alacahöyük, and the wider Hittite world. The visit to Hattuşa is most meaningful when bracketed by a half-day at the Ankara museum either before or after.
