 Though the original Fatimid palace complex, including administrative buildings and royal residents, no longer exists, modern scholars can glean a good idea of the original structure based on the Mamluk-era account of al-Maqrīzī.Perhaps the most important of Fatimid monuments outside the palace complex is the mosque of al-Azhar (359-61 AH/970-72 CE) which still stands today, though little of the building is original to its first Fatimid construction.Likewise the important Fatimid mosque of al-Ḥākim, built from 380-403 AH/990-1012 CE under two Fatimid caliphs, has been rebuilt under subsequent dynasties.
