The Chiana and Orcia valleys contain many extremely significant sites in terms of both artworks and medieval and Renaissance history.
On the slopes of Val di Chiana stand settlements of Etruscan origin such as Montepulciano, with a wealth of medieval and Renaissance monuments (works by Sangallo, Vignola, Peruzzi, Michelozzo etc…) as well as well-known centres like Cortona and Chiusi.
On the slopes of Val d’Orcia: Pienza, S.Quirico e Radicofani mark the Roman Via Cassia, which follows the ancient Via Francigena route for some distance; not to mention other lesser-known but equally charming towns such as Monticchiello, Castiglioncello del Trinoro, Montefollonico, La Foce and Castelluccio. History and Art are thus the two major cultural and tourist attractions, but we can add a third element: the thermal spas: Bagno Vignoni, Terme di S. Filippo and San Casciano in Val d’Orcia; Terme di S. Albino and Chianciano on the slopes of Val di Chiana.
If thousands of people come to visit these places, and often decide to stay, it is because the scenery today remains the same as the landscapes of the great painters.
