Archaeologists on Wednesday unveiled a fortified structure from the time of the King David on the Israeli-occupied Golan Heights that sheds light on the borders of a Biblical Israeli ally. The 3,000-year-old fort, found near the Jewish settlement of Hispin ahead of works to build a new neighbourhood, is believed to have belonged to the Geshurites, King David's allies. Locally quarried basalt boulders form the metre-and-a-half (five-foot) thick walls of the hilltop complex. Barak Tzin, who directed its excavation for the Israel Antiquities Authority, estimated that it covered more than 1,000 square metres.
