Warren's Shaft Water System
Discovered: City of David, above the Gihon Spring, Jerusalem
From: (c. Bronze and Iron Age phases; construction and use of individual passages remain debated)
Warren’s Shaft is a deep natural vertical opening connected with a network of tunnels and passages near the Gihon Spring. The shaft was named after Charles Warren, who explored it in the nineteenth century. For many years, it was thought that residents drew spring water through the shaft without leaving the protection of the city.
Later excavations showed that the shaft is a natural geological feature and challenged the idea that it was originally designed as a water-drawing shaft. Archaeologists also identified different phases of the surrounding passages. The system remains valuable evidence of how ancient Jerusalem developed access to water, but its precise use at the time of David is uncertain.
2 Samuel 5:6–8; 1 Chronicles 11:4–6 (capture of Jerusalem); 1 Kings 1:33–39 (Gihon). Identifying the biblical water shaft or passage with Warren’s Shaft is disputed.
