The hall has a rectangular ground plan. Based on a square middle room, it is divided by 12 pillars, all spanned by pointed arches, into 20 compartments of two different forms: two narrow oblong ones each on three sides of the central area (see picture 5) and two smaller square ones each in the adjacent corner areas. Between the pillar pairs that frame an oblong compartment stands a column each with octagonal shaft and multifaceted capital, which is formed by small geometric cells (muqarnas). Towards the side of the windowed entrance wall, the hall is only one bay deep. The courtyard side with its second row of pillars functioned as a kind of entrance portico, being once opened by four high pointed arches within the outside wall. The central area is covered by a high dome. Supported by four massive pillars, it rests on muqarnas pendentives – triangular-shaped with tiered rows of geometric cells –, and is topped by a round lantern with small columns plus pointed cupola. The other parts are covered with elongated, flattened vaults and small domes according the respective compartment form
