The walls surrounding the Lower Town of Tilmen Höyük had an opening at about the middle of the eastern front for the monumental entrance of the Middle Bronze II, consisting of an advanced body (K-6) and a main gate (K-1) connected by walls. The two structures were separated by a courtyard: at least one basalt lion (probably two) sculpted in the round was placed along the outer gate, flanked by two towers. The main gate, with a single room, was also equipped with two towers. The access was regulated by two openings crossed by a covered drainage canal, while a double wooden portal blocked the outermost passage.
