Drawing of the defensive slope at Ashkelon, showing the slope’s major defensive features: A mudbrick tower, now badly deteriorated, of the Middle Bronze IIC period (1600–1550 B.C.) is at upper left. Another massive mudbrick tower, at upper right, was built by the Philistines in Iron Age I (1200–1000 B.C.). In front of the Philistine tower lie thick layers of artificial fills that formed the slope, or glacis, of the Philistine rampart. Rising behind it are remnants of Hellenistic fortifications, made of medium-sized ashlar blocks of sandstone.
