The Tentennano Fortress is located in Castiglione d'Orcia, in the district of Rocca d'Orcia, and is a castle that, since 1100, has continued to be subjected to continuous disputes between the Republic of Siena and the Salimbeni family. Its position on the Via Francigena made it an absolutely privileged location.
In 1262, the original structure of the castle was demolished and it was completely renovated. The Republic of Siena had received 20,000 florins from the Salimbeni family to brave the battle of Monteaperti between the Ghibelline troops of the Siena and the Florentine Guelph troops: the Tentennano Fortress was given as a pledge. In 1274, the fortress became permanently owned by the Salimbeni family. The stories and legends of the time tell us that Santa Caterina da Siena stopped in this place. Today, the fortress hosts art exhibitions and can also be visited on foot after a challenging but pleasant uphill walk. Once you get to the terrace, you can enjoy an unforgettable view of the Val d'Orcia.
