Gihon Spring or Fountain of the Virgin, also known as Saint Mary's Pool, is a spring in the Kidron Valley. It was the main source of water for the Pool of Siloam in Jebus and the later City of David, the original site of Jerusalem.
One of the world's major intermittent springs – and a reliable water source that made human settlement possible in ancient Jerusalem – the spring was not only used for drinking water, but also initially for irrigation of gardens in the adjacent Kidron Valley, which provided a food source for the ancient settlement.
The spring rises in a cave 20 feet by 7, and is located 586 yards northwards of the Pool of Siloam.
