The main dwelling was a cottage divided into two rooms, one of which probably served as a vestibule; the floor was carved into the rock, as were the holes accommodating supporting wooden structures. The covering was probably made of cloth or skins, anchored to the ground by pegs. Near the cottage there were also some small facilities, perhaps just tents with a pole in the middle to support them.
Outside, three hearths, a chamber used as stove and two large holes, filled with pieces of charcoal and obviously used for storing burning material, have been identified.
The pottery finds consist of impasto earthenware only, in part locally produced: ollae of different sizes, covers and containers for foodstuffs.
On the whole, the settlement has the appearance of a 'camp', equipped with those facilities (hearths, stocks of wood and stove) necessary in order to survive for some time in a mountain environment.
Probably the Etruscans that settled at Piari came from Versilia, where, at this time (end of VIIth - VIth century b.C.), they were already well established (S. Rocchino; Via del Poggione; Baraglino; Casa Baldi; Acquarella). Maybe a group of scouts, spurred by the search for new natural resources to exploit, reached the Vagli basin across the Tambura pass. The Etruscans penetrated into the upper and middle Serchio valley only in a later period (Ponte a Moriano; Buca di Castelvenere), when the settlement of Piari had already been long abandoned; in particular, in the upper valley, some very small settlements were placed along the main cross-Apennine routes.
In the IIIrd century b.C. a Ligurian settlement, of which only a terrace wall, founded on natural debris covering the remains of the Etruscan settlement, once again occupied the site of Piari.
