City of Armageddon Lost Worlds : Season 2 Episode 13

Located on a rocky plateau overlooking the Dead Sea, the now-ruined fortress of Masada once had walls 1400m long and 4m thick, storehouses, barracks, an armory, a palace and massive cisterns filled with rainwater. Designed to withstand any invader, it became the scene of one of history's most bloody sieges... a siege that ended in mass suicide.
