The Middle Bronze II city was characterized by a partition into acropolis and lower city, both surrounded by their own circuit of casemate walls. These walls were made up of a series of rooms, which were positioned side by side and created a continuous external front joined at intervals by fortresses located in strategic defense points. The remains of long stretches of the outer wall, which continued around the lower town for more than 900 meters, are clearly visible on the surface, especially in the northern part excavated by the Turkish expedition.
