The origin of the mining activity is known since Roman times, which had its greatest development during the ‘400 – ‘500 by the Serenissima Republic, which, through the “investiture”, concessions to private individuals for research and cultivation of mines, favored the emergence of various companies for the extraction of silver, lead, zinc, barium and other minerals.
The activity continued with less intensity in the following centuries, until relatively recent times, for the extraction of galena and manganese, kaolin and quartzite.
Today there is no longer any mining activity; some traces of this activity remain, such as tunnels still open or closed, depressions and accumulations of excavated material in some areas.
Mountain archaeology and ethnoarchaeology allow to rediscover the ancient ways of human settlement and exploitation of the resources of the territory since prehistory.
