This overall symmetrical arrangement and the courtyard's opening on the south was designed to provide a visually grand approach to the Sattiniya from the Arsat an-Nil gardens. The palace wing on the east side of this courtyard was historically the residence of the sultan's hajib (chamberlain), while the wing on the west side of the courtyard included facilities such as kitchens and storage rooms. The west wing is also topped by an observation belvedere called the Menzeh ar-Radhi, with views on the courtyard and the garden.[1]:483[2]:397
