English: The Qalawun complex is a massive complex in Cairo, Egypt that includes a madrasa, a hospital and a mausoleum. It was built by the Sultan Al-Nasir Muhammad Ibn Qalawun in the 1280s; some thirty surviving mosques were built during his time.

The Qalawun Complex was built over the ruins of the Fatimid Palace of Cairo, with several halls in the Palace. It was sold to several people until it was finally bought by the Sultan Qalawun in 1283 AD. The structure resides in the heart of Cairo, in the Bayn al-Qasrayn, and has been a center for important religious ceremonies and rituals of the Islamic faith for years, stretching from the Mamluk dynasty through the Ottoman Empire.

The Mausoleum of Sultan Qalawun in Cairo is considered by many to be the second most beautiful mausoleum, succeeded only by the Taj Mahal in India. Al-Nuwayri (an Arab Historian), has said in his book Nihayet al Irab (The Utmost Desire), that the Mausoleum was not intended to become a buriel site, but a Mosque and a school, and that it was first used as a tomb when he died, and hosted his body. His body was kept in the Cairo Citadel for two months until the tomb was ready to replace the Citadel's Burial location, later when Qalawun's son died, he too was buried in the Mausoleum. The mihrab of the mausoleum is often considered as the most lavish of its kind. This is in contrast to the mihrab of the madrasa, which is less grand in size and general esthetics. With a horse-shoe profile the mihrab is flanked by three columns made of marble. The Mausoleum later on, and under the mamluks included a Museum for Royal Cloths of those buried in it.

The Mausoleum of Qalawun is significant in that it’s dome served as a ceremonial center for the investing of new emirs. Indeed the dome was a symbol of new power, a changing of the guard, signifying a new center of Mamluk power, which enjoyed great prosperity at the time. The Mausoleum's Dome was demolished by the Ottoman Governor over Egypt Abdul-Rahman Katkhuda and was then rebuilt in Ottoman architecture, However the Comite for reservation of Arab monuments built another dome to replace that in 1908 [Wikipedia.org]
