Castiglione d’Orcia is a comune (municipality) in the Province of Siena in the Italian region of Tuscany, located about 90 kilometres (56 mi) southeast of Florence and about 40 kilometres (25 mi) southeast of Siena, in the Val d’Orcia, not far from the Via Cassia.
Castiglione d’Orcia borders the following municipalities: Abbadia San Salvatore, Castel del Piano, Montalcino, Pienza, Radicofani, San Quirico d’Orcia, Seggiano.
The settlement is mentioned for the first time in 714, when it was a possession of the Aldobrandeschi family. In 1252 it became a free commune, but lost its independence in the following century to the Republic of Siena, which entrusted it to powerful families like the Piccolomini and Salimbeni. Later, Castiglione was part of the Grand Duchy of Tuscany and, from 1861, of unified Italy.
