The spaces around the arch are decorated with carved stucco and crowned by a carved and painted wooden canopy, which likely date from the 16th or 17th century during the later Alaouite period.[3][2] The arch itself is occupied by an ornate wooden screen known as an anaza; an outdoor or "summer" mihrab for those prayers taking place in the courtyard.[3][3] The anaza has two doors, between which, in the middle, is a decorative composition with a mihrab shape containing a carved inscription in Arabic calligraphy.[3] This feature is reminiscent of an equivalent creation added by the Marinids to the courtyard of the Qarawiyyin Mosque.[10] The current anaza here, however, dates from 1678–1679 CE (1089 AH), during the reign of Sultan Moulay Isma'il.
