The Ferriera Mill is located along the Farma bay trail, on the ‘delle Ferriere’ hiking trail. Built in the mid-thirteenth century, it is still very well preserved. The Roccatederighi washhouses dating to the early 1900s were restored. In the center of Montemassi, you’ll find an ancient cistern that once provided water to the entire community. Many local buildings still host private cisterns (a past custom).
Near the provincial road that leads from Giuncario to Ribolla, in the vicinity of the Bruma River, you can find a series of fifteenth-century ruins, mostly covered with brambles (123 metres on the left bank in the Roccastrada Municipality and 60 metres on the right bank in the Gavorrano Municipality) of the Muracci weir along the Bruna, the oldest total brick weir across a river. They’re known as ‘I Muracci’ due to local tradition. Once a fish farm, the idea was conceived by the Republic of Siena in 1462, designed in 1468 and finally completed in 1481. Just eleven years after its completion, the fish farm was destroyed by flooding that severely damaged the countryside.
