The Well of Souls (Arabic: بئر الأرواح, romanized: Biʾr al-Arwaḥ; sometimes translated Pit of Souls, Cave of Spirits, or Well of Spirits), is a partly natural, partly man-made cave located inside the Foundation Stone ("Noble Rock" in Islam) under the Dome of the Rock shrine on the Temple Mount (Haram al-Sharif) in Jerusalem.[1] During the Crusader period, it was known to Christians as the "Holy of Holies",[2] referring to the inner sanctum of the former Jewish Temple, which, according to modern scholarship, was probably located on top of the Foundation Stone.[2]
The name "Well of Souls" derives from a medieval Islamic legend that at this place the spirits of the dead can be heard awaiting Judgment Day,[3] although this is not a mainstream view in Sunni Islam. The name has also been applied to a depression in the floor of this cave and a hypothetical chamber that may exist beneath it.
