The Kabba (Arabic: ٱلْـكَـعْـبَـة “The Cube”) is a building at the center of Islam’s most important mosque: the Al-Masjid Al-Ḥarām in Mecca, Saudi Arabia. This is the most sacred site in Islam. Muslims consider it the “House of God,” and it has a similar role to the Tabernacle and Holy of Holies in Judaism. Wherever they are in the world, Muslims are expected to face the Kaaba when performing prayer.
One of the Five Pillars of Islam requires every Muslim to perform the Hajj. Parts of the Hajj require pilgrims to make Tawaf circumambulation seven times around the Kaaba in a counter-clockwise direction. Pilgrims also perform Tawaf during the ‘Umrah (or Lesser Pilgrimage). However, the most significant times are during the Hajj, when millions of pilgrims gather to circle the building within a five-day period.
