They really are ruins and will not be rebuilt. We walked the street to get to the top. It is not far. You are able to park just on the inside of the lower part of the village. The fort was not much of a site to see because it was in bad shape, and truly ruin. In Etruscan times it was a good fortress situated 900 feet high in the hills. The Romans had control during the Early Middle Ages. The Longobards controlled the region for years, but hen the Aldobrandeschi family over the area. They held the territory until 13th century of the outlying forts/villages. They held the territory convering the villages of Sassoforte, Montemassi, Roccatederighi. Siena took over control but eventually lost the power.
The fort is a"pure" ruin and a great disappointment once you get to the top. It was sold in 1770 to a wealthy person in 1770 and since then nothing has been done to improve the structure.
The main part of the village we are standing in. There is not much to it, other than some houses on both sides, but the age of the structures is impressive. You enter the village from a small via and then it drops right into the first wall and the still occupied castle, now private. Most of the main part of the village is form the15th-17th century and very peasant feeling. The buildings are all of formed rock and not much is elaborate. Italian visitors form the country come her during the summer months to "get away from it all" We met a couple form Turin and they were here two weeks just to stay and remain at peace while they walked the streets with the dog.
Once you walk into the village, you will note there basically are only a couple of places to find anything to eat. This is a working village where residents eat at home, and not a tourist hangout so restaurants are not needed much. There is one small deli that has some basic items, and I recall one cafe/trattoria and very small.
