The museum consists in two sections, one with archaeological objects from the Fortezza delle Verrucole, the other with findings that date back to the Metals Age. In the first room you can see some findings of the middle of the Bronze Age (XVth century b.C.), of the Cultura delle terramare, found during the construction of the kindergarten of San Romano. Some other findings, coming from the hill of the Fortezza delle Verrucole, date back to the recent Bronze Age and the final Bronze Age. From another hill, the Monte Vigne, come the other fragments of pottery showed, that attest the important presence, in the IIIrd century b.C., of the Liguri in the territory.
The second room is dedicated to the Fortezza delle Verrucole, described in its evolution, beginning from the castle, attested by the historical sources, already in the 1207. The big military structure, that was constructed on the basalt of Verrucole, can be seen, in its extension, from the rooms of the museum. The archaeological materials accompany the historical events and the various architectural transformations of the building, mostly from the half of the XVth century, when the Estensi controlled the Garfagnana. The Estensi, infact, to consolidate their power, made the castle become a Fortezza, as attested by the rich documentation.
