Grey tufo threshold for the road facing Room 14. Contains cuts for some sort of covering for the entrance. In phase with SU 5470 and abutted by tufo slab paving north of street. Different grey tufo from original red tufo phase. Th use during later phase, possibly in use earlier. The long groove cut in the stone suggests a very large opening, probably for some sort of taberna fronting on the road.
