A portion of tufo slabs, probably used as a floor. Seemingly at the same level as the tufo slabs 7320 in the northeast corner of room H15, but unlikely to have been a part of the same original surface, given that these slabs seem to have been spoliated and recut before they were laid here, around blocks 7323 and 7326. This probably functioned as some sort of use surface, perhaps associated with the circular mortar feature to the southeast (7384).
