Castiglione d’Orcia is a village nestled in the spectacular countryside of the Val d’Orcia, a region marked by the typical geological white, lunar “crete,” or “clays,” formed through ages of transformation. These lands are known for their clayish hills, where the slopes form sinuous bends with rounded corners, and in steeper areas, the “biancane,” barren semi-spherical (or cone-shaped) domes.Like the rest of the area, Castiglione is not only worth visiting for its rolling hills; it’s also bursting with artistic works from the entire region.
