A structure in Mecca to which Muslims from around the world make their pilgrimage. They believe it to be the house of God on earth, built by the angels themselves before the beginning of time and later restored by the prophet Abraham and his son Ishmael. Muslims consider the Kaaba to be the holiest place on Earth.
On the ‘umra (lesser) or hajj (major) pilgrimage performed in Islam, Muslims are required to circumambulate the Kaaba counterclockwise seven times.
Even in pre-Islamic Arabia, however, people flocked to the Kaaba for religious worship, making Mecca an important center for religion and trade. During that time, it housed statues of local deities, and parchments containing Arabic poetry, known as the mu‘allaqat, were hung on its doors. In 630 AD, when the Muslims conquered Mecca, the Prophet Muhammad cleared the Kaaba of statues and once again dedicated it to the one God.
The Kaaba is also primarily significant in that it marks the qibla for Muslims. The cube-shaped building, which is now roughly 15 meters high and approximately 10 x 12 meters at its base, has undergone several phases of restoration since the seventh century AD.
The Kaaba is made of gray stone and marble, with its interior containing three pillars supporting the roof. It is almost always covered in a black cloth known as the kiswa, which was historically made in different countries, such as Egypt, and transported in a caravan procession all the way to Mecca. The kiswa is changed annually.
