The Kaaba, a large stone structure constituting a single room with a marble floor, lies at the heart of the Holy Mosque (al Masjid al Haram) in the Holy City of Makkah. The Kaaba is Islam's holiest building. It now stands some 60 feet high and each side is approximately 60 feet in length. The Kaaba is the focal point around which the Holy Mosque is built. The four walls of the Kaaba are covered with a black curtain (the Kiswah) which reaches to the ground and is fastened to the Shadharwan with copper rings.
