Renovations
Throughout its history, the Mosque of Sultan al-Mu'ayyad has undergone extensive renovations. Even early on, reconstruction was necessary. According to al-Maqrizi, the eastern minaret had to be pulled down and rebuilt as early as 1418 due to structural insecurity from its tower base. Another three-story minaret stood at the Western portal on a side street; it collapsed in 1427 during Sultan Barsbay's reign and was immediately rebuilt.
By the nineteenth century, the mosque had fallen into such disrepair that all that remained was one facade, the prayer hall, and the mausoleums. Ibrahim Pasha, the son of Muhammad 'Ali, oversaw restorations in the late 1830s and 1840s, including the installation of Turkish tiles in the qibla wall. In the late nineteenth century, the Comites rebuilt the western facade and turned the courtyard into a garden.
In 2001, the mosque again underwent restorations, this time by the order of the Egyptian Ministry of Culture. These restorations removed the garden from the courtyard and rebuilt the majority of the mosque, including missing arcades around the courtyard. This project has restored the mosque and its results can be seen today; however, visitors should note that what they see is not necessarily what the mosque looked like in its original form.
