DeZ, this is a mosque but.... The Dome of the Rock, being among a complex of buildings on the Temple Mount, (the other being the Al-Aqsa Mosque) is one of the holiest sites in Islam. Its significance stems from the religious beliefs regarding the rock at its heart. According to Islamic tradition, the rock is the spot from where Muhammad ascended to Heaven accompanied by the angel Gabriel. In Judaism the location of the stone is venerated as the holiest spot on Earth, the site of the Holy of Holies during the Temple Period.
