The wall around the mihrab is decorated with stucco carving and topped by windows with intricate stucco screens.[1] The stucco decoration around the arch of the mihrab itself is likely dates from the original Marinid design, but the decoration further above and around this is more likely from the later Alaouite period, in the late 17th or 18th century.[2] The square space formed by the rows of arches intersecting in front of the mihrab is distinguished by more elaborate arches with lobed or lambrequin outlines (a type seen elsewhere in Moroccan and Nasrid architecture) and decorated spandrels.[3] The arch directly in front of the mihrab and across from it has muqarnas-carved intrados.
