In 2013, trenches were opened on the north, east, and south fronts of the structures exposed to date. On the north front, excavation of the well continued, and this revealed that it was connected to the cistern to the west, but only volcaniclastic material from the 472 A.D. eruption was dug out of it. Close to the well, a trench was opened along the external north wall of the charcoal deposit. Here, a substantial deposit of material from the 472 A.D. eruption was noted that also ran below the original floor level of the area, as suggested by the level of the building’s foundation offset. The 472 material lay directly on the ashy deposit from the 79 A.D. eruption. Above this, there was a dolium impression cutting into the ash later, a low wall and steps leading to the well area.

A new room was identified along the eastern side of the site, perhaps the first belonging to the villa itself, covered by a layer of rubble, probably the result of the eruptive phase, over which lay the thick deposit of volcaniclastic material. The floor level was reached in this area: the black and white mosaic was very patchy and showed traces of postholes.

On the south front several sections of wall were identified, of which one seemed to be of particular interest as it made it possible to establish a stratigraphic sequence in which all the walls relating to the villa seemed to be earlier than those of the bath building. Lastly, also on the south front, a terracing wall on a north-south alignment was identified, which probably divided the open-air area paved in opus signinum into two.
