At Serra, near Vado, in September 1957, during works in a clay quarry, three case tombs
, of which one empty, were found. The cases were made of six slabs of local stone and measured approximately 35x35x30 cm.. The first, belonging to a man, contained an olla
with the ashes of the dead and some bronze fibulae
, covered by an upturned bowl; a small vase of impasto
, a black glazed
cup with horizontal handles and a few iron fragments were also found. Inside the second case tomb was an olla containing charred bones together with a cover bowl; a large fragment of dolio
; seven bronze fibulae; spiral bracelet
in bronze, decorated with engravings; two silver wire rings and a few amber beads: this goods, with its ornamental articles, shows that it was the tomb of a woman. The typology, as well as the goods, make the necropolis referable to a Ligurian settlement of the end of the IIIrd
- beginning of the IInd
At the same time, inside the quarry, a small "cippo a clava"
with cone-shaped trunk, slightly sunken cap and small conical top, was found. The cippus, referable, for its typology, to the Vth
century b.C., is what remains of a former Etruscan necropolis.
Besides these, a large number of graves containing no goods and which could not be dated, have also been discovered.
