Khirbet Qeiyafa (Elah Fortress; Hirbet Kaifeh) is the site of an ancient fortress city overlooking the Elah Valley. The ruins of the fortress were uncovered in 2007,[2] near the Israeli city of Beit Shemesh, 30 km (20 mi) from Jerusalem.[3] 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.[4] A number of archaeologists have claimed that it might be the biblical city of Sha'arayim or Neta'im[5] and that the large building at the center is an administrative building dating to the reign of David where King David might have lodged at some point.[6][7] Others are sceptical, and suggest it might represent either a North Israelite, Philistine or Canaanite fortress.[8]
