The Castle, built around the XIII century, belonged to the Ottieri family. Despite the expansionist designs of the Aldobrandeschi family and, subsequently, of the Orsini family, the Ottieri managed to keep control of the castle until 1616, when it was ceded to Cosimo II de’ Medici. The Ottieri family remained the feudatory of the land and held their possessions until the half of the XIX century. Castell’Ottieri preserved its typical structure as a feudal settlement with its church, village and castle, right at the entrance of the village. The only remain of the castle is the fortification, made up of a five-storey quadrangular defensive tower connected with a semicircular tower. Particularly evident on the façade are three coats of arms made of Peperino, a volcanic tuff, one of them belonging to the Ottieri family. Once you have reached this little village, you can’t miss the visit to the Church of San Bartolomeo. The most interesting feature of the Church are the beautiful frescoes housed in it.
