This season work concentrated on two different areas of the production quarter (previously investigated in 2013-2014). Two trenches were opened, which proved to be very interesting as they revealed evidence of the transition from the imperial to the late antique phase. In order to reach the imperial levels it was decided to remove a substantial part of the collapses present in the area, specifically in the immediate vicinity of the metalworking structure to the west (area A), and in the far east-south-eastern area (area C). The removal of the collapses made it possible to read the entire area and, above all, understand the zone adjacent to the late antique metal workshop in all its phases, which saw numerous collapses and rebuilds. In fact, to the east of the workshop (not excavated this year) another production structure with various phases was completely excavated down to a floor in opus spicatum. The presence of a threshold led to the identification of part of a well-made road paved with medium sized basoli. This seemed to reach the quarter at the height of the new structure presumably linked to another production phase associated with the workshop.

It is interesting to see that all the events that occurred in this ambit, although attributable to successive phases can be dated to within a precise chronological arc that reaches the 6th century A.D. and coincides perfectly with all phases of the workshop. The dismantling of the collapses made it possible to clarify the presence of continuous rebuilds and the restoration of a pillar, making it ever more plausible that the entire area suffered extensive damage from the multiple earthquakes that took place in these periods. The excavation of a trench in area C was just as significant, where the presence of an interesting structure interpretable as a caupona had been noted. This was excavated down to the first imperial phase, revealing different patches of floors, which although small attest the long use of this room. The levels of collapse also had to be removed here.

It seems clear that the entire structure underwent numerous modifications and rebuilds and the last of these attests its use as a structure for producing objects in metal and other materials, although presumably in this case it was not a workshop-forge. Of note, the presence in room A and room C of small and very small bronze coins, collected there to be melted down.
The finds study has shown that amphorae and coarse wares of Italic production were the predominant ceramic types. A substantial number of African and Eastern amphorae were also present. Kitchen wares were predominant among the coarse pottery, but there was also a significant amount of African table and kitchen wares. Glass and metal finds were also present.
