During the campaign which took place in September 2009 work was undertaken in five sectors, investigating the Bronze Age levels.

1) In quadrants F1R, F2D, G1O, G1P, G2A and G2B work continued towards gaining a better definition of the operations that went into the creation of the ditch, in particular in the first phase, attributable to the Late Apennine period. The investigation of burnt structures datable to a late phase of the Proto Apennine period also continued. In the eastern part of the excavation area the exploration of the Proto Apennine structures, although not completed, uncovered two sub-circular combustion structures, whilst the rest of this zone appeared to be occupied by yellowish crushed limestone make up, partially overlaid by a clay surface.

2) In sectors G2H, H2E and H2I the exploration of levels datable to the Early Apennine period continued. These levels abutted the base of a stretch of related walls which now appear as trapezoidal in shape, with the short side on the interior. Towards the north-east the levels were intercepted by the ditch facing dating to the end of the early Iron Age and therefore it was not possible to establish their original width. By the south-eastern corner a hearth was identified in a small depression in the ground surface.
The southern edge of the Early Apennine levels was constituted by the Proto Apennine walls: here investigation of the front part of the covered postern gate, identified in the previous campaign, continued.

3) In G2M, G2N and G2R the internal face of the Proto Apennine wall, and its transformations, was investigated.
This internal face seemed to have been robbed of most of the stones that must have constituted its front which was then rebuilt with irregular stones.

4) In quadrants G2Q, G3C and G3D investigation of the Sub-Apennine levels continued. A wide clay surface was exposed which, to the north, seemed to go beyond an alignment of large stones, whilst to the north-west it was cut by a shallow sub-circular pit full of cobbles. This accumulation may be linked to the use of the large cylindrical pit found just to the north.

5) In a vast area corresponding to quadrants F3D, F3G, F3H, G3A, G3C (part), G3E, G3F and G3G levels dating to the early Sub Apennine and Late Apennine periods were explored. In several of these quadrants a make up of soil mixed with yellow limestone was removed. This had probably been laid at the beginning of the late Bronze Age in order to pave a large space in correspondence with the track leading to the settlement. This arrangement seemed to replace an earlier one, datable to the late Apennine period, in which the ground surface had been consolidated with gravel. The traces of a structure delimited by a curving element of earth mixed with yellow limestone dated to the latter phase.
