Centre of the island: The 2011 investigation of a dwelling terminated with the uncovering of a surface made up of stones (US 481), of US 448, and of layer US 477; the 2012 campaign completed the excavation of this Final Neolithic structure. It appears that the layers excavated this year also date to this period as forms and materials of Lagozzian type, such as transverse arrowheads and stone blades, kidney-shaped weights, spindle whorls, and Breno type elements continued to be present. As regards US 488, the mixed soil composition and the small quantity of fragmented sporadic finds it contained, suggest this was a layer of dumped material. The excavation exposed a stone and ceramic floor (US 483) below which was a layer of sands, silt, and clay, US 462. In some places it filled small holes that had naturally opened in the sands and the gullies formed by the erosion which in several points had dislocated or removed the surface (US 486).
Three green stone axes were found in quite close proximity in US 462. One was very fragmented, only a small section of the cutting edge was intact, the smallest had a slightly damaged cutting edge. The largest axe was very well-preserved and had been placed inside a hole.

Shoreline areas and south-eastern area: In 2009, given the need to define the total extension of the of this exceptional archaeological deposit in order to ensure its correct conservation and safeguarding, a general survey was made using a Multibeam. This examined the shoreline and the make-up constituted by different sized stones (which to the north overlay the early Neolithic timber structures) to the east and west. This year a systematic underwater survey was carried out. An examination was made of the medium and large boulders (situated at the base of the scarp, which bordered the make-up and the raised area with stones, a sort of “dam” continuing to the north/north-west towards the Biandronno shore). It was seen that along the eastern shore, starting from the mooring, towards the south, there was a substantial concentration of piles, including the remains of a palisade. Other pile structures were identified to the south-west in the shallow water, as well as along the eastern shore and to the north-west on land.

The underwater research led to the discovery and investigation of the concentration of piles seen in 1863 by Antonio Stoppani and Desor e.De Mortillet in the south-east part of the island. An area of 90 m2 was surveyed and recorded and samples taken from the piles. Three other concentrations of prehistoric piles were discovered in the north-western and northern areas (an area investigated in 2006 and datable to the early Neolithic period: 4910-4580 B.C.). Core samples were taken both in the water and on land along two axes (N-S and E-W), traced so as to pass where there was a known stratigraphic sequence and, when possible, a known date.
