Masada is an ancient fortification in the Southern District of Israel situated on top of a mesa. Located on the eastern edge of the Judaean Desert, it overlooks the Dead Sea. Herod the Great fortified Masada between 37 and 31 BCE. According to Josephus, the siege of Masada by troops of the Roman Empire at the end of the First Jewish–Roman War ended in the mass suicide of 960 people, the Sicarii rebels and their families hiding there.
