Casemate Wall is a defensive system that surrounded mound cities in the Land of Israel from the Late Bronze Age and especially during the Iron Age. The sphincter wall consists of an outer wall and an inner wall. Partition walls were placed in the empty space between the walls, with the aim of creating rooms. The rooms had access from the city and other rooms in the wall. The inner rooms were sometimes used as storage or living rooms. In times of war they were sometimes filled with dirt and earth and thus provided the city with more protection than any solid wall. Many towers were often built between the wall, the width of which exceeded the width of the wall. In the Land of Israel, gates to the city called cell gates were sometimes incorporated into the wall, which were wider than the wall and had several rooms to the right and left of the gate.
