A watching brief undertaken on the site a residential complex to be built at the foot of a hill, in an area where a mid-late Bronze Age necropolis and a second period Iron Age tomb were already known, identified various occupation phases within an alluvial sequence.

The earliest phases, dating to the Recent Bronze Age, were attested by rubbish pits and post-holes, whilst in the Roman period the area was used for agricultural purposes attested by evidence of channels. These agricultural features cut two Iron Age burials. Covered by earth tumuli they were surrounded by large circular enclosures formed by sandstone slabs standing vertically within a narrow foundation trench.

Tomb 1 may be interpreted as a cenotaph, as it did not contain a cinerary urn despite being intact and showing no signs of having been disturbed. Tomb 2, cut by the Roman channelling, contained grave goods which had been fragmented by disturbance in antiquity, thus it was not possible to fully interpret the burial ritual. The remains of an Etrusco-Corintian pyxis and a carenated bowl of a type that is widespread in southern Piemonte was found inside the remaining half of a globular urn with burnished decoration on its exterior surface. It is not known whether the pyxis was placed inside the urn or had functioned as a lid. The other elements of the tomb group were a carenated drinking cup, a belt buckle and two fibulae. The burial dates to the second quarter of the 6th century B.C., with materials that are similar to the final phases of the Ligurian necropolis of Chiavari and the Golasecca necropolis of Castelletto Ticino.
