The Kaaba is a large cuboid-shaped building inside the mosque known as al-Masjid al-Haram in Makkah, Saudi Arabia. Muslims believe that the Kaaba was built by the command of Allah. The Kaaba's original architecture has remained the same for centuries.
History
Before Prophet Muhammad
According to Islamic sources, the Kaaba was a place of worship for angels before the creation of men. After the creation of Adam, the Kaaba was built by him. According to Qur'an, it is the first house on Earth.
The Kaaba was buried under the sand by the Noah's flood. After a period of time, it was rebuilt by Prophet Abraham and his son, Prophet Ishmael.The Kaaba was a place of monotheism for centuries. Then Amr bin Luhayy brought an idol to the Kaaba. After that, the Kaaba became a place of pagan belief.
After Prophet Muhammad
The Kaaba began to be managed by Muslims in 630 AD. Prophet Muhammad removed the idols. Also, the Kaaba was cleaned with sacred water (Zamzam) under his guidance.
The general architecture of the Kaaba remained the same until 1630 because people wanted to keep the original architecture. Only simple repairs and small decorations were made during this long period of time. In 1630, three walls of the Kaaba were heavily damaged by a storm. Then, it was restored by Murad IV, 17th Sultan of the Ottoman Empire. The Kaaba has remained the same after this renovation.
Religious Significance
The Kaaba is the holiest place in Islam. Muslims believe that the Kaaba is the House of God (Baitullah). Prophet Mohammed said the Sacred Mosque (Masjid al-Haram) is one of the three most important mosques on the Earth.
Muslims are required to make a pilgrimage (hajj) once in a lifetime to the Kaaba. As it is the most holy place in Islam, all Muslims pray towards this when they perform the five fardh (necessary acts mentioned in the Qur'an) Salat or prayer. At the end of Hajj season, there is a holiday called Eid al-Adha (English: Festival of Sacrifice).
