Northern stretch of the western wall of the room west of the corridor connecting the central courtyard and the stairs. The eastern wall of this room - between slab floors 5662 and 5661 - seems to have been robbed.
This wall is probably part of a taller wall judging from its height and certainly part of the central room of the western part of the middle terrace, in connection with wall 5545. The missing southern end could be due to later robbery activity. The plaster on the surface might be the facing.
Brick arch between 5664 and 5665 (5757), Broken-tufo slab and small rock below 5757 (5758), Rectangular cut in bedrock into slab floor 5726 (5759), and nearby walls 5664 and 5665
