Built in the late 18th century, the Bonano Mill was restructured in 1999, reviving its old structures. It is sited on the homonymous stream which, by means of deviations, supplies the water needed to drive the paddle that makes the grindstone turn. Today private property, it is still used to grind chestnuts and maize. A short distance upstream, it is possible to visit the Bonano Ironworks, another significant example of the old and productive manufacturing activity of the Casentino.
