Masada is a shadow of its former glory two millenniums ago. Yet the ruins convey the fortified sanctuary was worthy of Herod the Great, the ruler of the Herodian Kingdom of Judea. An impenetrable wall encircled the 18 acre complex. It was about 5,000 feet long and 13 feet high. This outer defense was guarded by 30 watchtowers measuring 66 feet high. Inside were two magnificent palaces with swimming pools and bathhouses. Additional features included a synagogue, storerooms and cisterns plus barracks and an armory. Finally, sufficient crops and livestock were raised on the plateau for a sustained supply of food.
