The fortified settlement was built in medieval times at two existing religious buildings, a church and a church, and was controlled by the Maggi family, also known as cotton Lords, nobles in that era clashed to the Dominion of the Aldobrandeschi.
Around the middle of the fourteenth century the Maggi subdued the castle in Siena, together with that of Montepò, which at that time was held by them; some years later the place was contested by the families of the Tolomei and Salimbeni, before Siena talking retook control.
The cotton castle looks like a form of settlement ruins, surrounded by the remains of an unusually shaped triangular walls; the large size of the area are similar to those of the main villages in the province of Grosseto.
At the eastern side of the triangular walls are visible architectural elements that are, arguably, the remains of the ancient Church.
On the Western side of the wall, a door leads into the Summit square, where the remains of walls and those of some other religious building civic buildings, including of course the Palace of the rulers.
