The northernmost of these rooms, which can be accessed directly from the northeastern corner of the courtyard, consists of an indoor patio or courtyard covered by a high cupola ceiling.[1][2] The layout of this patio is similar to the Chamber of the Twelve Columns in the Saadian Tombs, consisting of a square delineated by twelve marble columns arranged in groups of three at each corner, around which runs a gallery space.[4] Another mihrab is set into the eastern wall, while a small side-chamber is set into the western wall. The upper walls and the areas around the mihrab and doorways are decorated with carved and painted stucco featuring arabesque and epigraphic motifs typical of Moroccan architecture. At the center of the patio is an ornate fountain, and while the cupola ceiling above primarily features painted and carved wood.
