It is located at Bayn al-Qasrayn on al-Mu'izz street and like many other pious complexes includes a hospital (bimaristan), a madrasa and mausoleum.

[3] The structure is situated in the heart of Cairo, on the prestigious Bayn al-Qasrayn street, and has been a center for important Islamic religious and court ceremonies and rituals for centuries, stretching from the Mamluk dynasty through the Ottoman Empire.

[5] The funerary complex of Sultan al-Mansur Sayf al-Din Qalawun, including both madrasa and mausoleum reportedly took 13 months to build, and was under construction from 1284 to August 1285.

"[3] In addition to employing brutal labor practices, Sanjar also illegally acquired properties and forcibly evicted their inhabitants to complete the complex.

[3] Despite the controversy surrounding its construction, after its completion, the complex was considered one of the most beautiful buildings at that time, where it included a school (madrasa), a hospital (bimaristan) and a mausoleum, with an intricate dome.

[1] Historians claim that the columns holding the mausoleum structure were made of granite, marble, and other materials that were taken from al-Salih's (Qalawun's master) palace and citadel in Roda Island.

[6] Following an earthquake in 1302 that destroyed many structures in Cairo, al-Nasir Muhammad, the son and successor of Qalawun, rebuilt the complex and its minaret in a campaign to restore the damaged mosques.

[7] Architect Pascal Coste used the complex as one of his sources for his book Architecture arabe: ou Monuments du Kaire, mesurés et dessinés, de 1818 à 1825.

[8] As identified by Eva-Maria Troelenberg, Coste's drawings sought to adjust and define the angles of the structure to reimagine the building as a modernized urban space.

[4] Upon entering through a slight, horseshoe-arched portal, the cruciform madrasa is to the left with four iwans arranged around an open court with a pool in the center.

[10][4] The façade was constructed using ashlar blocks and consists of varying sizes of pointed-arched panels that come together to enclose single windows.

[4]  The façades of the madrasa and mausoleum are further connected by a gilded inscription of the complex's founder and important dates in the building's inauguration and completion.

[2] The mausoleum consists of a great rectangle that includes four piers and four columns, arranged so as to form an octagon on which rests a high drum surmounted by a dome.

[10][12] The use of glass mosaics points to the Umayyad tradition as seen in the Dome of the Rock; the revival of this medium during this period in Cairo serves to legitimize the Mamluk sultan's rule within an Islamic history.

[11] The hospital offered many amenities to the sick and poor in addition to medical treatment, including drugs, shelter, food, and clothing.

[11] Information about production of drugs for medical treatment, research,[11] and teaching that occurred within the hospital have been gleaned from a waqf documents from the time.
