- Ancient water tunnel that was dug under the City of David in Jerusalem
- It is 1750-feet (530m) long and was carved during the reign of Hezekiah to bring water from one side of the city to the other due to a threat by the Assyrians to destroy Jerusalem.
- Both the Gihon Spring, which is connected to the tunnel, and the Siloam pool at the end would have been used by ancient inhabitants of the City of David
- 2 Kings 20:20; 2 Chronicles 32:30 Descriptions of Hezekiah’s construction of the tunnel
- John 9 describes Jesus’ healing of a blind man at the Pool of Siloam, the end point of Hezekiah’s Tunnel.
