Construction work on a site between via Pertinace and Vittorio Emanuele II exposed further evidence of the of Roman Alba Pompeia. This appeared to belong to what was probably a wealthy residence facing onto the south side of insula XLII, corresponding with the last decumanus minore before the town’s south wall. The limited archaeological stratigraphy still preserved in the area was heavily disturbed by modern and recent construction work. It was constituted by a wall on a north-south alignment built of cobbles and stone slabs, associated with two types of floor on either side of the wall, which presented foundations built against the terrain razed at this level. The two patches of floor seem to belong to an interior room of the domus, on the east, and a service room or canopied area, to the west. The first was made up of opus signinum, overlying a rougher make up in turn overlying a loose cobble foundation. On the other side of the wall was a simple beaten mortar floor, much less of which was preserved and which lay directly on the natural clay. The lower part of the mortar floor incorporated several cobbles of various sizes. The Roman levels, datable to between the 1st and 2nd century A.D. on the basis of the construction technique already identified in other parts of the town were cut by several post holes. These related to late antique and early medieval occupation of the area, not otherwise known due to the removal of the relative stratigraphy by modern and recent interventions.
