The place name probably comes from the compound of "piano", with the meaning of a "plain place", and of "castagnaio", coming this latter from the Latin "castanea", with reference to the plenty of chestnut-trees in the territory.

The foundation of the village of Piancastagnaio occurred during the Early Middle Ages. Since the beginning it was subdued to the jurisdiction of the Aldobrandeschi, who built an imposing fortress, that is still visible today.

During the next centuries the village of Piancastagnaio was quarrelled among the Aldobrandeschi's family, the monks of the close Saint Salvatore Abbey and the Visconti's family.

During the XII-th century the city of Orvieto first extended its influence on the village and then at the beginning of the next century annexed it to its domains.

Since the middle of the XIV-th century the village of Piancastagnaio was quarrelled between the Republic of Siena and the city of Orvieto up to the beginnig of the next century, Siena annexed the village to its countryside.

Piancastagnaio entered the "Captainship of Radicofani", remaining in such condition up to the middle of the XVI-th century, when the Republic of Florence, after having defeated the city of Siena, annexed Piancastagnaio to its domains.

From then started the domination of the Medici's Grand Dukes, who already governed Florence. At the beginning of the XVII-th century Ferdinando I of Medici gave the village of Piancastagnaio as a feud to Giovanni Battista Bourbon del Monte.

Some years later, by coming the Lorena's Dukes to the power at the beginning of the XVIII-th century, the feudalism was abolished. In 1776 Pietro Leopoldo of Lorena elevated the village of Piancastagnaio to the rank of autonomous common, having its own statutes.

The Lorena's domination lasted almost uninterruptedly up to the Unity of Italy, occurred on 1861 by the action of the King Vittorio Emanuele II of Savoia.
