It is one of the most famous castles in Aosta Valley, and for its architecture and its many towers and battlemented walls has become one of the major tourist attractions of the region.

Under Boniface I the castle reached its greatest splendour: it was a rich court surrounded by a vegetable plot, a vineyard and a garden where the lord and his guests could relax.

In 1895 architect Alfredo d'Andrade purchased it and started a restoration campaign to secure the damaged structures.

In 1935 a second campaign by De Vecchi and Mesturino completed the restoration and gave the castle its current appearance.

At the top of the stairs a 15th-century fresco features Saint George killing the dragon, while the walls of the balconies are decorated with images of sages and prophets and proverbs in old French.
