The Frantoio of Il Castagno with its 3000 olive trees, is a historic oil mill, the oldest in the area, which processes not only its own olives but also those of third parties. Before the renovation, the extra virgin olive oil was obtained with cold stone mills and the mill was also seen by its customers as a meeting place. Not only was excellent oil produced, but the farmers could also enjoy excellent bruschetta thanks to the presence of the fireplace.
