The opening as it read in 2010
Mosque of Sultan al-Muayyad is a Mosque in Cairo , Egypt next to Bab Zuwayla built by the Mamluk sultan Al-Muayad Sayf ad-Din Shaykh from whom it takes its name.1 Construction began in 1415 and the mosque was completed in 1421. It replaced a prison which was originally next to Bab Zuwayla .2The historian Al-Maqrizi relates that it was in the same prison that Sultan al-Muayyad was imprisoned while an emir by the ruling Sultan An-Nasir Naseer ad-Din Faraj. The future sultan suffered from such lice and fleas that he vowed should he ever come to power he would transform the prison into "a saintly place for the education of scholars". True to his word when he later came to be Sultan he commissioned this mosque to be built. The construction of the mosque was an ambitious project requiring 40,000 dinars and such a large quantity of marble that some of it was harvested from pre-existing structures. When it was completed a large ceremony was held to open it. The famous Shafi`i scholar Ibn Hajar al-Asqalani was appointed as a teacher here. Architecturally, this is one of the finest examples of Mamluk architecture in Egypt. Originally it had four front facades and entrances. The main portal to the mosque is decorated with fine muqarnas and kufic calligraphic script. The main door is a masterpiece of bronze work taken from the Mosque-Madrassa of Sultan Hassan . The dome is a typical example of Mamluk stone masonry with a cylindrical base and carved zig-zag pattern. Its interior is decorated with lavish inlaid marble work and the ceiling is painted in geometric floral patterns. It has a remarkably large pavilion compared to other mosques in the area with an ablutions fountain in the centre.3
