Right in the heart of the village is a water mill dating back to the 14th century which was used to supply wheat and flour for the entire area; there’s substantial evidence to prove that, in highly active periods, the mill produces 8 tons of wheat per day.
Several of the countryside’s details perfectly underline the close relationship between history and nature in this part of the area. This is especially present in the Grancia of Cuna, considered the best conserved ruins of a fortified medieval farm, built in 1224 by the municipality of Siena and the Hospice of Santa Maria della Scala on top of a former 12th-century hospice. Large and still perfectly conserved, the complex consists of a small walled village and a fortress-farm overlooking the square, which can be reached by passing the entrance tower. Outside the fortified centre stands the small Church of Santi Jacopo e Cristoforo, from 1314. Not far from there is the Parish Church of Corsano – in the typical Romanesque style – founded in the 11th century and dedicated to St. John the Baptist.
