Tufo ashlar 5482 was cut by 5356 on southern face and is only exposed slightly as it was built into the foundation of later cement wall 5348 and thus appears to continue under it and floor 5320 to the East. It seems to be associated with an earlier phase represented by 5486 and 5488 and cement walls (5348, 5349, 5350, 5351) and floor 5320.
