The settlement is divided into different groups, placed both on Mount Pisone itself and on the neighbouring relief of Castellaccio, from where pottery, dating between the end of the IVth
and the first decades of the IIIrd
century b.C., comes. The archaeological exploration concentrated on the top of Mount Pisone where, in two separate areas, major terracing works, achieved with the help of stone blocks, some of which roughly hewn and levellings of gravel mixed with earth, have been identified.
The dwellings, made entirely of wood, were built on these largely artificial terraces. To the south, in particular, the remains of two buildings have been located; one of them, rectangular in shape, still retained its pavement made of trodden earth, crushed stones and sandstone slabs, as well as an inner stone shoulder and two hearths, maybe shared with the building next door.
Among the finds we have, though only in very small quantity, black glazed pottery
of both Etruscan and Roman (from Lazio) production; however, most of the tableware used in the settlement, in particular cups and jugs decorated with red stripes and geometric designs, belongs to the local Ligurian production. Ollae
for kitchen purposes, covers, storage vessels and spindles
were also produced locally in a typical 'vacuolato' mixture. From the same settlement, finally, come pestles of polished stone, as well as articles for adorning and dressing up, such as fibulae
, a buckle, a piece of bracelet
, a vase-shaped green glass pendant and other necklace parts made of glass paste, some of which already attested in Ligurian tombs from the upper and middle Serchio Valley (Castelvecchio Pascoli
). On the whole, the finds show that the settlement of Mount Pisone was abandoned just before the middle of the IIIrd
century b.C., for reasons we ignore; at that time of relative stability and peace, the defensive requirements regarding the strategic position of the site had, in any case, fallen.
