Castello di Montepò, Medieval castle in Scansano, Italy.

Castello di Montepò is a medieval fortress in Scansano built with rectangular layout and four corner towers surrounding a central courtyard with brick-covered walls. The defensive architecture sits on elevated ground overlooking the surrounding vineyards and countryside.

The fortified structure arose around the year 1000 beside an ancient parish church. It was almost entirely rebuilt in the 14th century while controlled by the lords of Cotone. At the end of that century Siena took control and, in the following century, sold it to the Sergardi family, who turned it into a fortified farm in the Renaissance.

The castle's name, Montepò, is recalled in the estate's wine labels, and the property belongs to the Biondi Santi family, known for Brunello di Montalcino. Before them, the British writer Graham Greene stayed here and drew inspiration from the place. The complex is now part of a working wine estate rather than a museum.

The castle is a private estate of the Biondi Santi family and part of a working wine farm, so the grounds and vineyards are not open for walking tours. It stands in open countryside about 30 km east of Grosseto and north of Scansano, reached by rural roads; view the exterior and surrounding landscape from the public road.

The British writer Graham Greene stayed at Montepò and drew inspiration from it for his work. The property later passed to the Biondi Santi family, who run it as a wine estate within the fortified walls.
