Another Jewish fortress of ancient Palestine lying southeast of Qumran across the Dead Sea at a distance of only twenty kilometers. Qumran lies almost halfway, as the crow flies, between Jerusalem and Machaerus. This fortress was built or at least strengthened by the Hasmonaean Alexander Jannaeus after he subjugated Moab to the east of the Dead Sea sometime before 90 BCE. It was designated as a bulwark to fend off attacks by the Aramaic-speaking Nabataeans who occupied Petra and areas to the south. Destroyed by Gabinius, the governor of Syria, circa 60 BCE, it was rebuilt by Herod the Great, and his son Antipas murdered John the Baptist there.
