King al-Zahir Ghazi founded the Sultanate School to commemorate his sons. Its design features an open courtyard centered by a marble pool and surrounded by an arcade of arches resting on harmoniously proportioned marble columns. The school also boasts a muqarnas dome over the mausoleum chamber, showcasing the remarkable craftsmanship of Ayyubid muqarnas sculptors, and is adorned with a foundation tablet inscribed in elegant Thuluth script.
In the 16th century AD, the building was transformed into the lodge of the Naqshbandi Sufis. As a result, lectures continued to be held at Friday dawn and at sunset, and one of the rooms was converted into a manuscript repository that houses rare copies of Ihya’ and Ash-Shatibiyya.
The Syrian–Italian project of 2007 restored the dome using a blend of plaster, lime, and a glass fiber mesh. Furthermore, the school was reactivated in 2019 to serve as a tourist guidance center offering live Sufi music presentations during cultural festivals—thereby linking the living heritage with the historic structure.
