Rivalta di Torino is a comune (municipality) in the Metropolitan City of Turin in the Italian region Piedmont, located about 14 km southwest of Turin in the valley of the Sangone. It is home to a medieval castle, around which the town originated starting from the 11th century. The castle and the village were owned by the Orsini local branch until 1823. The castle has a massive appearance and was once accessed through a drawbridge, now replaced by a stone one. In 1836 French writer Honoré de Balzac was guest of the local lord, count Cesare Benevello, as testified by an inscription in the castle's court.
