The Kaaba, also spelled Ka'ba, Ka'bah or Kabah, sometimes referred to as al-Ka'ba al-Musharrafa, is a stone building at the center of Islam's most important mosque and holiest site, the Masjid al-Haram in Mecca, Saudi Arabia. It is considered by Muslims to be the Bayt Allah and is the qibla for Muslims around the world. The current structure was built after the original building was damaged by fire during the siege of Mecca by Umayyads in 683.
