The plan locates the wall’s extant remains, which include the offset tentatively identified as a tower. Extending to the north, the wall once enclosed the area around the Gihon Spring, where Reich and Shukron have found two more towers—the Spring Tower and the Pool Tower—from the Middle Bronze Age, about a millennium earlier than the eighth-century wall. Another tower, perhaps contemporaneous with the offset unearthed by Reich and Shukron, was excavated almost three decades ago by the late Nahman Avigad. It is located in Jerusalem’s Old City (near the top of the plan).
