Castello di Belcaro, Renaissance castle in Siena, Italy.

The Castello di Belcaro is a fortified complex enclosed by wedge-shaped walls, with buildings grouped around a triangular medieval courtyard and a main Renaissance courtyard paved in herringbone terracotta. The three-storey villa's neoclassical facade by Serafino Belli has eight axes of openings, and a marble plaque records a visit by Margherita of Savoy. A garden fills nearly half the walled area.

The building was commissioned in 1525 by banker Crescenzo Turamini, who had it built over the ruins of an earlier fortress. Giorgio di Giovanni and Baldassare Peruzzi contributed to its architectural design.

The chapel inside holds frescoes by Peruzzi showing scenes like the Judgment of Paris, still visible on the walls today. These artworks shape the character of the rooms and tell of the taste and interests of their time.

The castle sits about 5.5 km southwest of Siena, in the direction of Grosseto, reachable by a visible road. You can reach it from Siena's Porta San Marco and pass by a former Benedictine monastery on the way.

A stone inscription on the walls marks the occupation by Cosimo de Medici's forces during the 1554 siege. This carving shows the building's role in the conflicts of that period.
