Alacaköyük, located in 45 southwest of Çorum and 160 km east of Ankara, is an important center extending to 4000 B.C. The first one on four discovered structure floors belong to the settlement of Phrygians which represents 650 B.C. and later. The second floor which the remains still can be seen is dated to Hittite Empire period (1466-1190 B.C.). There is a magnificent Sphinx Gate in the southeast of the city. Orthostats depicting hunting scenes and religious ceremonies are placed to two sides of the gate. A big temple consisting of buildings rising around a courtyard is discovered.
The third culture floor is dated to Old Bronze Age (2500-2000 B.C.). Discovered king tombs are the most important finds of this age. Dead gifts consisting of golden, silver and bronze works indicates that these tombs belong to the dynasty. These works are preserved in the Museum of Anatolian Civilizations in Ankara; and some finds are preserved in Museum of Alacahoyuk.
