About
About Gihon Spring and Warren's Shaft (City of David water system, Jerusalem)
Jerusalem's Bronze–Iron Age life-support hydraulic complex: the Gihon Spring (Hebrew 'gushing'), Jerusalem's only perennial spring (600–1,200 m³/day), fortified since Middle Bronze II (1800 BCE) with the Spring Tower (cyclopean 15-m fortress) and canal, and accessed inside the wall via Warren's Shaft — a 13-m vertical karst chimney shored with Iron Age chiselled steps linking the plateau to the spring outside the wall. Reich–Shukron 1995–2015 argued Warren's Shaft was not Israelite Joab's entry (contra 2 Samuel 5:8) but a natural karst used in MB, with the Canaanite Siloam Channel (18th c BCE) and later Hezekiah's Tunnel (701 BCE) diverting Gihon waters to Siloam Pool inside the wall.
Demonstrates 1,500-year Jerusalem water security engineering from Canaanite to Judite.
Why it mattersJerusalem's hydraulic genesis — proves MB water engineering preceding Hezekiah and the Joab narrative.
