Khirbet Qeiyafa (Elah Fortress; Hirbet Kaifeh) is the site of an ancient city overlooking the Elah Valley. The ruins of the fortress were uncovered in 2007, near the Israeli city of Beit Shemesh, 30 km (20 mi) from Jerusalem. It covers nearly 2.5 ha (6 acres) and is encircled by a 700-meter-long (2,300 ft) city wall constructed of stones weighing up to eight tons each. A number of archaeologists have claimed that it might be the biblical city of Sha'arayim or Neta'im and that it might contain the ruins of King David's palace. Others are sceptical, and suggest it might represent either a Judahite or Canaanite fortress.
