Giloh. According to Aharon Kempinski, this plan of Giloh, an Iron Age site near Jerusalem, shows a square structure, top, left, similar in shape and details to the Mt. Ebal structure that Adam Zertal identifies as an altar. The plan has been drawn by Amihai Mazar, the excavator of Giloh. Mazar identifies this building as a watchtower, built in Iron Age II (1000–586 B.C.) and reused in the Middle Ages. Mazar’s plan shows a wall built around the Iron Age settlement that, according to Kempinski, closely resembles Zertal’s temenos wall at Mt. Ebal.
