The 2011 excavations at Coppa Nevigata uncovered several Bronze Age phases. Exploration of the Proto-Apennine walls (circa 1700 B.C.) in the eastern zone continued, during which the point where they began to bend towards the south-east was identified. In this area, another postern gate was documented, close to what appeared to be an opening situated at about 1 m from the base of the walls themselves and blocked during restructuring in the Apennine phase. The second postern gate, situated in sector F2H, was fully excavated down to the base. Its large covering slab was preserved.

Levels dating to the Recent Proto-Apennine (14th century B.C.) period were investigated in the area in front of the postern gate. The levels showed signs of an extensive fire. Several fragments of baked-clay with impressions of canes/stakes were uncovered, presumably part of the west side of the quadrangular structure uncovered in previous years, together with a large circular kiln/hearth.

The badly disturbed remains of a structure delimited by a low wall and with a fill of crushed yellowish limestone mixed with earth can be dated to the Early Apennine period (15th century B.C.). It was probably one of a series of defensive structures situated along a line running parallel to the first Proto-Apennine walls. Skeletal remains were found on the occupation surface associated with this structure, situated not far from the Proto-Apennine walls themselves.

In the same phase or in the Late Proto-Apennine period the part of the first wall towards the settlement was removed and a roughly-built frontage was constructed. This phenomenon was also seen in sector H2P, where a bread oven was also identified, situated in the inner part of the presumed postern gate mentioned above. Between the Early Apennine period and beginning of the Late Apennine, the oven was partially dismantled and a substantial quantity of earth rich in yellow limestone accumulated. It was on this level that the Recent Apennine walls were built. These walls were in turn were disturbed when, during the Sub-Apennine period, two circular structures were built abutting them.

In the south-eastern part of the excavation, a new area was opened (H3F) bringing the total area to circa 120 m2. Here, parts of two cylindrical pits were uncovered, similar to those uncovered in previous years in the area north-west of the trench opened by the bulldozer. In the rest of the area numerous combustion structures came to light, including at least one bread oven, with up to three overlying floors built of pottery fragments and separated by the laying of clay surfaces, presumably representing the same number of rebuilds.

In a last area, the Recent Sub-Apennine levels were excavated down to, the layer of earth mixed with crushed yellow limestone already seen in other sectors in previous years, where it was present. In almost the entire area investigated, this was overlain by a cobbled surface comprising small stones and marine cobblestones. This was probably a third reorganisation of the area. Several postholes were documented, which cannot for the moment be associated with a defined structure. Part of a cooking slab was also found. Several fragments of Mycenean-type pottery, a stone weight and a number of metal fragments from unidentifiable artefacts were also recovered, as well as a tanged knife, the small nails for attaching the handle still preserved.
