The Orcia wine route was born in 2003 and has its headquarters at the foot of the Rocca in Tentennano di Castiglione d'Orcia.
13 are the municipalities included in the DOC Orcia: Buonconvento, Castiglione d'Orcia, Pienza, Radicofani, San Giovanni d'Asso, San Quirico d'Orcia, Trequanda, Abbadia San Salvatore, Chianciano Terme, Montalcino, San Casciano dei Bagni, Sarteano and Torrita of Siena.
The element that unites the territory on which the Strada del Vino Orcia winds is the landscape, one of the most characteristic and fascinating of Tuscany, perhaps the most beautiful countryside in the world.
In 2004, UNESCO included the Val d'Orcia in the world heritage of humanity, the first rural area to be awarded with this recognition, defining it in its motivations as a "landscape icon".
