The proto-historic site of Brunku S’omu is situated in the territory of Villa Verde (OR), in central-southern Sardinia, on the east side of Monte Arci. This research project involving excavations and survey began in 2013. During this second campaign, two structures were excavated: structure 16, begun in 2013, situated to the north of structure 1, and structure 18, north-east of hut 5. Students from the University of Cagliari and the Complutense University of Madrid participated in the excavations.

In structure 16, partially investigated in 2013, a series of new levels were identified that constituted the hut’s occupation phases. These layers were removed down to natural, formed by large blocks mixed with reddish sterile soil. The hut floor, made up of patches of cobblestones and beaten earth was built over this making use of the tops of the natural boulders. There was a large sub-quadrangular niche in the north-eastern wall and a semi-circular niche in the west wall. The excavation of structure 16 was completed. The layers contained archaeological materials datable to the final phases of the Final Bronze Age.

Excavation of the area outside hut 16 continued in the west and north sectors in order to expose the exterior facing of the hut and to check for the presence of a structure, not yet found, but probably existing immediately to its north.

A new hut, 18, a few metres east of hut 16, was excavated. In this area, the removal of the surface layers of humus, leaves and small stones exposed the walls of a sub-quadrangular structure (4.70 × 4.40 m), with the entrance to the west. The hut was filled by a large collapse characterised by brown, loose, sterile soil. The collapse was uniform across the structure and contained large stones from the upper levels of the walls. The excavation was halted at -5.70 m where a layer of very compact earth was reached.
