The most famous Islamic site in Jerusalem is the Dome of the Rock (Qubbat as-Sakhrah). An impressive and beautiful edifice, the Dome of the Rock can be seen from all over Jerusalem. It is the crowning glory of the Haram es-Sharif ("Noble Sanctuary"), or Temple Mount. The Dome of the Rock is not a mosque, but a Muslim shrine. Like the Ka'ba in Mecca, it is built over a sacred stone. This stone is believed to be the place from which the Prophet Muhammad ascended into heaven during his Night Journey to heaven. The Dome of the Rock is the oldest Islamic monument that stands today and certainly one of the most beautiful. It also boasts the oldest surviving mihrab (niche indicating the direction of Mecca) in the world.
