"The cliffs on the east edge of Masada are about 1,300 feet (400 m) high and the cliffs on the west are about 300 feet (90 m) high; the natural approaches to the cliff top are very difficult. The top of the plateau is flat and rhomboid-shaped, about 1,800 feet (550 m) by 900 feet (275 m). There was a casemate wall around the top of the plateau totaling 4,300 feet (1.3 km) long and 12 feet (3.7 m) thick, with many towers, and the fortress included storehouses, barracks, an armory, the palace, and cisterns that were refilled by rainwater. Three narrow, winding paths led from below up to fortified gates."
