Unfortunately, this first pioneering research and clandestine excavations, helped by the fact that the cave wasn’t protected, removed the most interesting part of the archaeological deposit.

The various excavations have made us discover a stratigraphic sequence that documents the human frequentation in the cave from the middle bronze age (1600-1350 BCE) until the early Neolithic (impressed pottery ware culture, 5800 – 5000 BCE).

Amongst the numerous materials, today exhibited in the aforementioned museums, there are ceramic vessels, of which the typical cups with axe shaped handles of the initial phases of the middle bronze age. For these discoveries the Pollera cave is considered today one of the most significant contexts to understand the passage from the early bronze period to the middle bronze age in northern Italy.

Out of the artefacts that came from the excavations the presence of large containers with chords that were used for storing food is interesting. These are a clear evidence of a frequent and prolonged frequentation of the cave by the community of the bronze age.
