Revered by both Jews and Muslims, the site is believed to be the oldest continuously used intact prayer structure in the world, containing the burial sites of the patriarchs and matriarchs of the Jewish people. According to the Abrahamic religions, the cave and adjoining field were purchased by Abraham as a burial plot. Known to Jews as the Cave of Machpelah, the site is considered by Jews to be the holiest place after the Temple Mount. For more follow @michaelchristopherbrown.
