The "Balmetti"
Characteristic of this area of Canavese, these are natural cavities in the mountain, adapted over the centuries by the inhabitants to cellars and food storage, where the temperature is constant thanks to the circulation of air caused by complex natural geothermal phenomena. The term balmetti derives from balma, meaning shelter under rock, cave.
