The Great Mosque of Mecca, commonly known as al-Masjid al-Ḥarām (Arabic: اَلْمَسْجِدُ ٱلْحَرَامُ‎, romanized: al-Masjid al-Ḥarām, lit. 'The Sacred Mosque'), is a mosque that surrounds the Kaaba in the city of Mecca, in the Hejazi region of Saudi Arabia. It is a site of pilgrimage for the Hajj, which every Muslim must do at least once in their lives if able, and is also the main phase for the ʿUmrah, the lesser pilgrimage that can be undertaken any time of the year. The rites of both pilgrimages include circumambulating the Kaaba within the mosque. The Great Mosque includes other important significant sites, including the Black Stone, the Zamzam Well, Maqam Ibrahim, and the hills of Safa and Marwa.
