Remains of an ashlar wall that seems to belong to the original phase of construction in this part of the 'piazza', in phase with tufo base 7145 and ashlar walls 7142, 7143, 7149, etc. This block seems to continue the line of wall 7098 to the east (inside of Room 3). For the moment, the nature of the space between the eastern limit of this block and the western limit of wall 7098 is unclear, in part due to the presence of wall 7080, but also because there is an irregular grey tufo stone (not documented) at the eastern end, which may belong to some kind of slab floor or threshold.
