Rich collection of minerals from the Ossola valleys divided according to the most characteristic paragenesis. Built inside one of the oldest stone buildings in the country, once the seat of the municipality and elementary school, the mineralogical museum was born from the collection that the parish priest, Don Giovanni Bonomo, wanted to donate to his community. The collection includes 3333 specimens, cataloged by name and locality, coming almost exclusively from the Ossola valleys, with the predominance of the Antigorio and Formazza valleys, where the deepest geological structures known throughout the Alpine building emerge.
