Châtelard Castle is a medieval castle in the town of La Salle in the Aosta Valley, Italy.
Rodolphe Grossi, the bishop of Aosta from 1243 to 1257, is said to have constructed the fortress. The castle, which was built in the shape of a round tower and was modeled after the fortified structures of Peter II, Count of Savoy, to whom Grossi was a close advisor, is first mentioned in records from 1248. The Châtelard castle is made up of a tall circular donjon which is attached to a squared-off dwelling house that is encircled by an unorthodoxly shaped walled enclosure to fit the terrain.
