 It is located on a dry plateau about 1.5 km from the northwestern shore of the Dead Sea, near the Israeli settlement and kibbutz of Kalya.
 The Hellenistic period settlement was constructed during the reign of John Hyrcanus, 134–104 BCE or somewhat later, and was occupied most of the time until it was destroyed by the Romans in 68 CE or shortly after.
