In the interior, the dome of al-Gulshani rests on corner supports made up of four tiers of decorative muqarnas niches. On the exterior, the dome rests on a simple single-stepped octagonal zone-of-transition. Above this plain base, the dome of al-Gulshani is decorated in carved patterns of exquisite craftsmanship that prefigure the even more elaborate and magnificent decoration of Sultan Qaitbey’s final tomb. Here, the star motifs are repeated five times on the circumference, so that they do not align with the eight windows in the drum, nor with the sides of the octagonal base. This asymmetry enhances the free-flowing aspect of the decoration. The decorative panels in carved stone on the facades likewise feature extremely sophisticated and complex geometric patterns, some based on nine- and seven-pointed stars.
The prayer hall adjoining the tomb resembles a qa‘a – a hall in which the central part has a slightly sunken floor and is faced on both sides with open-fronted liwan rooms. In mediaeval Cairo, this arrangement was often used in reception halls of residential houses, and sometimes also in religious buildings.
The interiors must have been impressive, but they have been stripped of all their decoration. Only the painted ceiling in the entrance vestibule remains.
After conservation carried out by ARCHiNOS in 2018 – 2019 with the European Union funding, the building now hosts various events as part of a neighbourhood cultural hub operated by the Sultan Foundation with support from the Drosos Foundation.
