Sultan El- Muayyad Mosque in Cairo, next to Bab Zuwayla built by the Mamluk sultan El-Muayyad Saif El-Din Shaykh, is one of the finest examples of the Mamluk architecture in Egypt. The construction started between 1415- 1421; it replaced a prison and became a land mark at Cairo. Sultan El-Muayyad spent 40,000 dinars on its construction.
There was a great ceremony for its opening when El-Muayyad and his Mamluk entourage came down from the Citadel. According to reports, the water basin in the middle of the vast courtyard was filled with liquefied sugar and sweets were offered to attendees.
In addition to the Sultan’s lavish endowments, El-Muayyad madrasa became one of the most prominent academic institutions of the 15th century. A large library was built and eminent scholars of the day filled professorial chairs such as; Ibn Hagar El-Asqalani.
The mosque originally had four facades and four entrances; the two main facades are the one parallel to Bab Zuwayla on the site of the Fatimid southern city wall which was rebuilt in 19th century, and the facade perpendicular to Bab Zuwayla on its left, with the main portal.
