The best-preserved medieval fortress in Valle d'Aosta, this many-turreted castle was built in the mid-14th century by Aimone di Challant, a member of a prolific family related to the Savoys. The castle, which used a double ring of walls for its defense, would make a perfect setting for a fairy tale, given its pointed towers, portcullises, and spiral staircases. The 15th-century courtyard surrounded by wooden balconies is elegantly decorated with well-preserved frescoes.
Inside you can see the kitchen, with an enormous fireplace that provided central heat in winter; the armory; and the spacious, well-lighted rooms used by the lord and lady of the manor. If you have time to visit only one castle in Valle d'Aosta, this should be it.
