The 2010 campaign, undertaken during September, excavated in five areas, investigating the Bronze Age levels in particular.

1)In sectors F2H, F2R, G1O, G2A excavation of the structures identified in previous campaigns continued and a more in-depth investigation of a stretch of Proto-Apennine wall in the first of these sectors began. As regards the structure, just to the north four post holes were identified which must have held the timbers supporting the roof. Traces of the beaten floor surface preceding the one already uncovered were also identified. In the northern part of F2H a trench was dug in the fill of the walls dating to the early Apennine period, built with earth mixed with crushed yellow limestone, in order to check whether this was the site of the exterior of the postern gate identified in sector F2N. The front exterior of the postern gate was preserved to the height of the roof and was excavated to most of its original height, reaching the base of the late Proto-Apennine levels, constituted by levels of earth mixed with yellowish limestone.

2)In sectors G2H, H2E, H2I (north part) exploration of the late Proto-Apennine levels, situated outside of the first fortifications and showing traces of burning, continued. This revealed a lower part of the covered postern gate, still without reaching its base. The Proto-Apennine walls were preserved here to a height of at least 2 m, but again the base was not reached. In sector H2H, at the base of the levels of burning dating to the late Proto-Apennine period, a circular hearth came to light. An earlier occupation phase dating to the same period was also identified. This was characterized by the presence of a cobbled surface and numerous post holes, which partly followed the line of the external face of the Proto-Apennine walls.

3)In G2R, H2I (south part) and H2O exploration of the inner face of the Proto-Apennine walls and subsequent rebuilds continued. In H2I and H2O, as already seen in G2M and G2N, this inner face was heavily robbed in antiquity and then the facing was roughly replaced. This facing was abutted by a certain quantity of yellowish earth. A new inner face was constructed above this and partially containing it. When the latter also fell into ruin, the remains were covered with a dump of clayey soil, on top of which, at least in part, a cobbled surface was created. In the early Sub-Apennine period this was also covered by an accumulation of yellowish soil. The southern part of sectors G2R and H2O had been heavily disturbed by the action of a bulldozer in 1979: this had largely removed the fill from the two large sub-cylindrical structures, similar to the other three uncovered previously in the adjacent sectors, probably dug at the end of the late Sub-Apennine period.

4)In G2O, G2P, G3B, G3C exploration continued of the Sub-Apennine levels together with the excavation of the fill of a semicircular, stone-built, post-Bronze Age structure. The late Sub-Apennine levels investigated in this area produced several metal fragments, some segments of sawn deer horn and a rock-crystal bead. These levels did not seem to relate to a definable structure: the presence of a row of large stones may perhaps be interpreted as a bench rather than the base of a wall. In two localized points there were traces of burning with the presence of vegetal fibres, perhaps planks relating to the flat roofing or an intermediate floor that had partially collapsed. The structure mentioned above, which appeared to have a semicircular plan but it cannot be excluded that it was circular, was seen to comprise several rows of overlapping stones, whose diameter increased towards the base. The exterior did not have a facing, which suggests that it may have been constructed by digging a large pit and resting the stones against its sides.

5)The ample area paved with gravel was not subjected to further investigation, however a number of adjacent sectors were excavated. In quadrant F3D, or rather in the L-shaped part of it not previously excavated below layer 1, the Sub-Apennine levels preceding the creation of the sub-rectangular structure present here were removed. In particular, in the one metre square quadrants F and G a concentration of pottery was uncovered, with indications that it was broken where it lay. To the south-east three new quadrants were opened (G3H, H3E). The first of the two had been largely disturbed by the bulldozer; in the remaining part and in H3E the archaeological deposit was preserved from 20 cm below present ground level. Several features were preserved, although discontinuously, including three cooking surfaces and accumulations of baked clay.
