The Masada.
Factoid: Masada is the site of the most dramatic and symbolic act in Jewish history, where in the year 74 C.E., its 960 inhabitants chose mass suicide rather than face certain capture, defeat, slavery or execution by their enemies. The account of the siege of Masada was related to Josephus by two women who survived the suicide by hiding inside a cistern along with five children. Masada is located at the top of an isolated rock on the edge of the Judean Desert and the Dead Sea valley, between Sdom and Ein Gedi.
