This section of wall appears to be one side of a threshold with SU 5362 leading from room 11 to area 10. The southern limit appears to be broken and may not denote the limit of the wall or room 11. The ashlar blocks from this wall and SU 5362 are not in their original locations, which may account for their differences in size and comparative levels. The thin brick coursework may have been present as can be seen in more complete walls in the room, such as SU 5366. If the southern limit is complete it may line up with an east-west wall (no longer present)to close off room 11. There is a tufo ashlar block running east-west which could have served as the foundation to such a wall.
