The excavation investigated the area situated immediately east of the room with mosaic floor found in 2012.

The eastern edge of the trench was extended by 7 m and the accumulation of late medieval material removed. An occupation layer relating to the paved building was exposed that extended across the entire excavation area and was characterised by the presence of several hearths. One of the latter, situated at the north-west trench edge, was bordered by a circle of stones and contained pottery datable to between the late 2nd and early 1st century B.C. (Campania B black glaze, balsamaria, a lamp and fragment of a terracotta statue) and numerous fragments of pig and sheep/goat mandibles.

In the southern part of the trench, this level was cut by late medieval buildings. In particular, the remains of a square construction, probably a small tower, and a stretch of a small paved road made up of bricks, broken tile and some archaic majolica fragments.

In the eastern part of the trench, a section of wall, identified the previous year, was completely uncovered, and was preserved to a length of 5 m. A bronze coin and an almost intact cooking pan datable to the late 2nd century B.C., were recovered from the earliest layer in phase with this structure, which abuts its west side. Likewise, the excavation to the west of the wall revealed an occupation level made up of a layer of grey clay with charcoal fragments, in which there was a hole filled with soil and numerous fragments of moulds, architectural terracottas, metal slag, and black glaze pottery dating to the late 2nd century. A preliminary interpretation of the wall, prior to extending the trench to the north to check whether it continues, suggests it was a section of an enclosure relating to a late phase when the sacred area was enlarged.
