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.
The Foundation Stone in the floor of the Dome of the Rock shrine in Jerusalem. The round hole at upper left penetrates to a small cave, known as the Well of Souls, below. The cage-like structure just beyond the hole covers the stairway entrance to the cave (south is towards the top of the image).

The Dome of the Rock is an Islamic shrine at the center of the Al-Aqsa mosque compound on the Temple Mount in the Old City of Jerusalem. It is the world's oldest surviving work of Islamic architecture, the earliest archaeologically attested religious structure to be built by a Muslim ruler and its inscriptions contain the earliest epigraphic proclamations of Islam and of the Islamic prophet Muhammad.
