The Holy Mosque
The holiest mosque in the world, the Haram Mosque has been much expanded from its original 7th-century form. Today it can accommodate up to 820,000 worshippers in air-conditioned comfort.
This huge mosque stands over the site of the Prophet Muhammad's house and tomb and is the second holiest mosque in the world after al-Haram in Mecca.
The Ka'ba is believed to have been built by Abraham and his son Ishmael. Enshrining a sacred stone, it is said to be first place on earth that was created. It is the directional focus of worldwide Muslim prayers.
