Cultivated in the provinces of Grosseto and Siena, these chestnuts thrive in the rich soil of volcanic rocks and sandstone found around Mount Amiata, one of the largest Italian lava domes, located in southern Tuscany, about 20km northwest of Lago di Bolsena, a crater lake of volcanic origin.
For many years, especially in the early 1900s, the delicious Castagna del Monte Amiata nuts were the main and, often only source of food for a major part of the population and therefore known as 'the bread of the poor'.
