Dome of the Rock
With the distinction of being the oldest existing Islamic building in the world, the Dome of the Rock is an important landmark of Jerusalem. On this site once stood the grand Second Temple of the Jews that was destroyed by the Romans. The Muslims built this dome which was converted into a Church by the Crusaders and back to a mosque by the Mamluks and Ottomans. A building with such a fascinating past and claimed to be significant by the three Abrahamic religions is closed to non-Muslims today.
