1 tufo slab which seems to be a fragment of floor paver, perhaps from the cutting of the slab floor 5726; we've also included in this same SU a fragment of tufo sitting on top of this slab. Its tilt and brokeness suggest that its placement was not part of the construction/function of the arch feature SU 5757 (oven? furnace?), but rather was dumped after the feature went out of use.
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
