History
The Castle of Cosona is a fortified architectural complex in Italy, situated in the rural locality of Cosona within the municipality of Pienza, Tuscany. Built during the fifteenth century, it later developed into a fortified farm and became the subject of several changes of ownership.
From fortified complex to agricultural estate
The site continued to serve agricultural purposes over the following centuries. In the nineteenth century, a rectangular building was added and converted into a granary. Its construction was commissioned by the Forteguerri family, whose heraldic coats of arms were placed on the building.
At the beginning of the twentieth century, the entire complex was restored according to plans by Arturo Viligiardi, an architect from Siena. In 1913, a chapel was established inside an existing agricultural building that had previously been used for other farm activities.
Cosona remains the center of the agricultural estate and is also used for rural accommodation, with seven independent apartments. Several sharecropping families lived within the complex until the 1970s.
Remains
Fortified buildings and infrastructure
The surviving complex is formed by several attached buildings arranged across fifteen sides. Their irregular grouping retains the character of a fortified agricultural settlement, while a square-section tower rises along the western front.
Western tower and cistern well
The square-section tower is the principal vertical feature of the western side. A cistern well built in 1659 supplied water for daily life at the castle and was restored in 1913 as part of the wider renewal of the complex.
Granary and chapel
The nineteenth-century granary has a rectangular plan and displays two heraldic coats of arms belonging to the Forteguerri family. Elsewhere within the complex, the chapel occupies a pre-existing agricultural building, preserving the adaptation of an earlier farm structure to a religious use.
