Muslim men pray beneath the massive stone enshrined at the Dome of the Rock in Jerusalem, Israel. Despite its appearance, the dome, called Qubbat as-Sakhrah in Arabic, is not a mosque.
Rather, it is a shrine built over the rock from which the Prophet Muhammad is said to have ascended into heaven. The site is also sacred in Judaism as the place where Abraham prepared to sacrifice his son Isaac.
Built on Temple Mount between A.D. 685 and 691, the dome is the oldest extant Islamic structure and one of the first Islamic monumental buildings ever constructed.
