The south side of the court is also arcaded, but not in the same fashion. The arcades are much shallower (·40 metre deep) and they are differently grouped. In the centre of the south wall there was a wide archway (4·20 metres wide) leading into room 29. This arch rose above the level of the arcade on either side of it and the chambers behind it were higher than the adjoining chambers (Plate 29, Fig. 1). On either side of the entrance there is an unusually large engaged column; beyond these columns there is a flat pier and an engaged quarter-column, followed by a niche ·80 metre wide covered by a shallow calotte (Plate 29, Fig. 2). Three more recesses, measuring in width 1·95 metres, 2·10 metres, and 2·50 metres, and separated from each other by engaged columns of about ·70 metre diameter, occupy the remainder of the façade. In no case is the capital preserved, but it is noticeable that all the columns swell outwards towards the top. The archivolts are ovoid, not horse-shoed. The first niche on either side of the small niches contains a door leading on the west side into No. 31 and on the east side into No. 42. The third big niche on the east side contains another and a smaller door which gives access to a stair leading to the roof (Plate 28, Fig. 1). The doors of Nos. 31 and 42 offer good examples of arch construction (Plate 29, Fig. 3). The arch is set back from the jambs and formed of an inner ring of concrete and an outer ring of stone voussoirs laid horizontally. The calottes covering the niches are of brick, but unlike the calottes on the other three sides of the court, the bricks are set horizontally and vertically and used in half and quarter lengths so as to form intricate designs which Dr. Reuther compares very aptly to the Hazârbâf motives so common in oriental woodwork (Plate 29, Fig. 2).
