The Well of Souls, is a partly natural, partly man-made cave located inside the Foundation Stone under the Dome of the Rock shrine on the Temple Mount in Jerusalem. During the Crusader period, it was known to Christians as the "Holy of Holies", referring to the inner sanctum of the former Jewish Temple, which, according to modern scholarship, was probably located on top of the Foundation Stone.

The Foundation Stone, or the Noble Rock is the rock at the center of the Dome of the Rock in Jerusalem. It is also known as the Pierced Stone, because it has a small hole on the southeastern corner that enters a cavern beneath the rock, known as the Well of Souls.
