During the 2013 season, several sectors were opened in the north-eastern part of the settlement, reaching as far as the border with the modern pathway that skirts around the fencing of the buffalo enclosure. At present, investigation of the continuation of the fortifications towards the south-east is blocked by this pathway. In order to make the best use of the available space in this direction, some of the excavation sectors were given a triangular or polygonal shape. The following trenches were opened: the south-eastern part of sector H2A (triangle), the south-western part of sector H2F (triangle), the eastern part of sector H2Q (rectangle minus a small corner), the south-western part of sector H2R (triangle), sector H3D (almost complete) and sectors H3C, H3G and H3H (complete).
In H2A, a row of large stones was uncovered that delimited an accumulation of earth mixed with crumbled yellowish limestone. This alignment presumably linked to the analogous structure uncovered in 2012, as there is only a small part missing, probably due to erosion.

In H2Q, the continuation of the Apennine walls (14th century B.C.: figs. 3-4) was identified, the frontage built on top of the proto-Apennine walls, together with the late Apennine quadrangular tower and the eastern forepart dating to the early Classical Apennine period. The front of the walls was also traced in the adjacent sector H2R and for a short length in H3D, where it began to curve to the south-east.

The structures exposed in G3E, where excavation continued below the floor surface of the open area consolidated with gravel, were also attributable to the same period. A series of levels were investigated that appear datable to the Classical Apennine period (14th century B.C.), some with a cobbled surface (fig.5).

A large structure was identified in sectors H3C and H3H. It was delimited to the south-west by a row of medium sized stones and characterised by the presence of a layer of medium-small stones (figs. 6-7) to the north-east. The latter’s north-eastern edge was not clearly defined: it is likely that its bad state of preservation on this side is the result of erosion due to the slope of the artificial rise. This structure, presumably datable to the 13th century B.C., appeared to post-date the Apennine walls and pre-date the last sub-Apennine levels preserved in situ and which cannot be precisely interpreted at present.

Several layers attributable to the 12th century B.C. were present in quadrant H3E, constituted by alternating layers of earth rich in organic elements and thin make ups of crushed yellowish limestone. This suggested a series of repeated episodes of occupation and the remaking of the floor surfaces. In this area, part of a circular or horseshoe-shaped combustion structure was exposed (fig.10). The make up for a small hearth was also identified in H3L (fig. 11).

An area extending across part of H3G a large part of H3F and the north part of H3L was investigated, across which baked clay fragments were present, some with thin plant impressions (twigs, canes). Also present in the area were the fragments of broken pottery vessels in situ (fig. 12).

Lastly, the fill of a large cylindrical pit – silos (fig.13), was excavated in H3G. One was already known in this area, and they were probably dug in the 12th century but filled with dumps of material from the successive centuries. The eastern part of another pit, previously identified in H3F, was also excavated.
