In 1375 Sha'ban founded and embarked on the construction of his own ambitious mosque, madrasa, and mausoleum complex in 1375, on the location of what is now the Maristan of al-Mu'ayyad, at the northwestern foot of the Citadel. It was lavishly decorated and, like his mother's madrasa, it had two domes (probably inspired by the double-domed mausoleums to the south of the Citadel, such as the Sultaniyya Mausoleum).[1] However, Sha'ban was assassinated in 1377, before his mausoleum complex was finished and ready for use.
