The Kaaba is the holiest place in Islamic doctrine, and it is located in Masjid al-Haram, in Mecca. Muslims believe that the Kaaba is Bayt Allah (the house of Allah), so everyone turns to the Kaaba in prayers. Pilgrims who come to Hajj (annual pilgrimage) or Umrah (pilgrimage outside the regular annual Hajj) come to go around seven circles around the Kaaba, which symbolizes unity in faith in one God. Unfortunately, only Muslims can enter Mecca, so a visit to this religious center is reserved only for them.
