This season’s excavations concentrated on the area between trenches I and II opened in 2014, on a north-west alignment, and a sector within trench II, immediately east of the tannery identified during the previous year.

In trench I, more rooms belonging to the domus, partially excavated during previous seasons, were uncovered. The first phase of the domus seems to date to the Augustan period. Four rooms were identified immediately south of room 6, which faced onto an open or semi-open area, interpreted as a long corridor providing access to the domus itself. The corridor was paved with a mosaic of white tesserae, with a double border of black tesserae. During the 3rd century AD, the complex was enlarged and new mosaic floors were laid, such as that uncovered in room 18. The polychrome mosaic has a geometric pattern decorated with vegetal motifs. The occupation of the structures during the 4th century and the abandonment of the building in the second half of the 5th century appeared to be confirmed. All the excavated rooms showed signs of reoccupation from this period onwards, with evidence for timber structures on top of the obliteration levels and wall collapses. This reuse probably continued until the 7th century.

In trench II, east of the tanning vats, the presence of a drainage channel was confirmed. Running west-east, it drained the wastewater from the tanning process and had masonry-built parapets and a tile floor. This area also presented evidence of heavy robbing and reoccupation of the spaces (originally attributed to a 2nd century A.D. phase) beginning in the mid 5th century and lasting until at least the 7th century. This involved the installation of dwellings with roofs of perishable materials and internal structures for food preparation and heating (cooking slabs and domestic hearths).
