SU5169 is the western wall next to the stairs. It covers the stairs and was built alongside the stairs to provide access between the upper and lower terraces of the building. It was very disturbed and the middle part was robbed out, which might be due to cut SU5165, located just east of the wall, or to the dumping activity that covered it the wall itself. It is truncated to the east by the foundation of the much later concrete wall SU5159.
