The rural area which the territory of Castiglione d'Orcia forms a part of is known as the Val d'Orcia: a sparsely populated area with an almost unaltered agricultural landscape compared to previous centuries. The beauty of this agricultural landscape in Tuscany is the reason for its status, obtained in 2004, as a UNESCO World Heritage Site. The historic centre of the village, of medieval origin, is situated at 540m above sea level and allows a marvellous view for kilometres.
In particular, you can look out over an imposing medieval defence tower rising out of the landscape at the Rocca di Tentennano, situated in the area of the "Rocca d'Orcia", just a stone's throw from the true centre of Castiglione d'Orcia.
The village's economy is based on two main activities: agriculture and tourism, and especially an activity which represents a combination of the two: Agriturismo 'agro-tourism,' where farms typically offer rooms and/or meals from their own produce. Within the boundaries of the municipality there are also some well-known hot springs: Bagni San Filippo. Tempted tourists can choose between private spas, which charge entrance, and the free, public ones.
