The Museum is a precious testimony of the intense activity of the mining community of Calceranica from 1800 to the second half of the '900. Although the first occasional processes are documented in the Mandola valley – the torrent that originates from the Vigolana and flows into Lake Caldonazzo – since 1600, the industrial exploitation of the deposit takes place mainly between the end of the Second World War and 1964 by the Montecatini Company with the extraction of pyrite used in the manufacture of sulfuric acid. In the Museum are exhibited objects and accessories of the individual equipment of the miners, from the oldest to the most recent, together with documents, photos, maps, drilling, ventilation and transport machinery and anything else that was used for the processing of the extracted material. A series of educational panels also present the geological structure and mineralization characteristics of the area. A few steps from the City Hall, in Piazza Graziadei, is the Monument to the Miner, carved in porphyry by the artist Mario Ricci. Inaugurated in 1991, it is 4.50 meters high and was erected by a group of former miners and the association Gruppo Culturale Miniera. Do not miss a visit to the Mining Park. The museum is open all year round and can be visited from Monday to Friday from 8.30 to 12.30 - free admission.
