Castello di Triana, Medieval castle in Triana, Italy

Castello di Triana is a stone fortress in southern Tuscany built on a rocky hilltop with rectangular towers and thick defensive walls. It overlooks the Albegna valley and the surrounding countryside from this elevated position.

The site is documented from 760, but the castle itself is first attested in 1216, when the division of Aldobrandeschi assets assigned it to the Santa Fiora branch. In 1388 Triana was bought by the Sienese Piccolomini family, who made it the seat of a rural lordship during the 16th century. They kept the castle and surrounding land until 1962, when it passed to the Società di esecutori di pie disposizioni of Siena.

The castle holds meaning for locals as a symbol of medieval power in the region and draws visitors interested in understanding feudal life. Walking through it gives a direct sense of how noble families defended and controlled their territories.

Access is via a steep path from Roccalbegna with some sections unpaved, so sturdy footwear is recommended. Guided tours are available during summer months by prior arrangement.

The castle passed to the Società di esecutori di pie disposizioni of Siena in 1962, after the Piccolomini had owned it since 1388. Its gentilizio chapel, the Cappella della Madonna di Loreto, was rebuilt in 1744 and holds an altarpiece of the Madonna and Child with Saints Francis and Catherine of Siena, a Sienese work of the 16th–17th century.
