The city was the capital of the Hittite Empire from the 17th to the 13th century BCE. It was included in the UNESCO World Heritage List in 1986. Hattuşa is located 4 km east of the Boğazkale district, southeast of Sungurlu district in Çorum province. The city was built on a mountainous area of approximately 2 square kilometers. Surrounding the city are walls constructed during the reign of King Suppiluliuma I (c. 1344–1322 BCE). Inside the city, there are administrative centers, residences of nobles, temples, and military structures. While members of the royal family lived in the upper part of the city, there was also a citadel within the fortifications. In the lower parts of the city, houses made mostly of wood and adobe were found, alongside agricultural fields and granaries that supported the city’s needs. Today, only the stone foundations of temples and palaces remain. The city was destroyed following the Bronze Age Collapse, leading to a disruption of social life until the Phrygian period. Later, the settlement was partially used by the Galatians but never regained the importance it held during the Hittite era.
