Wall constructed to fill space between room 22's threshold (5823) and SU 5658, forming a boundary between the interior of the room and the road to the south. The damaged condition of the top of the feature indicates that the wall was once taller than it currently stands.
Pillar related to a later occupational phase, which was a reuse of an earlier structure.
