Life at Tilmen Höyük was at its most glorious between the 18th and 15th centuries BC. After the capital city Hattusa, it was one of the grandest cities in Anatolia.
Excavations at the site have shown that it was an important city from 4000 BC until the latter part of the third millenium BC. Findings from the tumulus also reveal a connection and interaction between the cultures of ancient Mesopotamia and Syria and that of ancient Anatolia.
At the northeast of the tumulus there are round towers, 8 m in height, which are reached via a slope and 17 steps. The city consists of inner and outer city walls. The castle walls were made of large, uniform ashlar stone blocks, rising up from the ground, with their incredible size and weight adding to the overall magnificence of the city. The walls were built using a casemate design, with the massive blocks resting on each other. The original entrance to the city was in the east, with door lions guarding each side, but there were also two other smaller entrances, one on the northwest, the other on the southwest side of the city.
