The 2015 excavations once again took place in the urban area immediately adjacent to the bath complex where the Nilotic mosaic now in Cannara Museum was found.

Most of the walls uncovered in the area (as seen in 2014) were organic in plan and presented uniform construction characteristics, which showed they were not originally part of the baths complex. They were of earlier date and had a separate function, in many cases probably residential.

The 2015 excavations documented sections of wall that were repaired with robbed material indicating the transformation and reconstruction of old, deteriorated structures, evidence for the long period of occupation and use of the area. Dating of the structures and the reused material or associated finds was made difficult by the radical alteration to the related layers, which produced finds covering a wide-ranging chronology.

It is certain that the planning and building of the baths complex in the first decades of the 2nd century A.D. redesigned at least part of the previous urban layout in order to create links between pre-existing structures and the new complex and create access to the baths themselves. The 2015 excavations uncovered even more extensive sections of collapsed wall often placed to fill gaps between old and new walls, indicating that static support, levelling and drainage were all efficiently dealt with, redefining the new topographical, environmental, and architectural layout of the area.
The uniform and generalized razing of the wall crests and the formation of at least some of the dumps of materials found between 2013 and 2015, is the result of recent widespread agricultural activities.

The results of the 2015 were documented using the same methods as in 2014 with the aim of creating a single texturised 3D model of the baths and surrounding area using a photogrammetric survey linked to safe topographical points.

During the 2015 campaign, the excavation area was gradually extended to reach the eastern edge of the ancient city, not far from the baths complex. The structures of a modest house were uncovered. The walls, with a double facing made of small sandstone blocks bonded with mortar, were preserved to a low height. The presence of reused materials in the facings highlighted the precarious and rundown appearance of the building. The rooms that were exposed appeared to have a regular plan, were small and had floors formed by a thin surface of beaten lime laid at the level of the foundation offset.
The exploration also continued of the city wall in the area of the baths complex and a short stretch was exposed.
