Al-Masjid al-Haram (also known as al-Haram Mosque, Masjid al-Haram, Haram al-Sharif, Masjid al-Sharif and the Haram) in Mecca, Saudi Arabia, is the holiest mosque in the world and the main destination of the Hajj pilgrimage.
The mosque complex covers an area of 356,800 square meters and can accommodate up to 820,000 worshippers during the Hajj. The Masjid al-Haram (”Holy Mosque”) is the only mosque that has no qibla direction, since Muslims pray facing the Ka’ba in the central courtyard. (See The Ka’ba and Black Stone for details on the Ka’ba.)
