The museum was born in 1984 and it was complementary with the Mining Museum: it deepens some aspects of the mining activity concerning the area around Massa Maritttima.
The museum was in the medieval Armory Building (1442). The History and Archeology Department of the University of Siena took part in the project: the current exhibition offers an educational and didactic tour through the local mining history. There you will see a mineral exhibition, informative panels and miners tools.
The museum has been moved to the “Subterraneo” in Via Corridoni.
