Why come
The name means plain of the chestnut, and the forest that still climbs the slope above the town is what fed it for most of its history: sweet chestnut, sessile oak, beech. The town itself sits at 772 meters, built around a twelfth-century keep that passed to Siena in 1418 and to the Medici in 1559, and the palazzo built into its old defenses in the sixteenth century reads as the Medici layer set directly against the Aldobrandeschi one. Contrade named Borgo, Castello, Coro and Voltaia divide the centro storico for the August race, while the mining museum keeps the record of an industry, cinnabar and mercury, that ran on the mountain from Etruscan times until it closed in 1982 and that has otherwise left the town to the chestnut trade. What Piancastagnaio adds up to is a place where a volcano's slope has supplied, in turn, timber and food, ore, and a festival calendar, and where the built town still carries each of those histories as a separate, legible layer rather than a single blended one.
