The castle was built in the 14th century by the Counts of San Martino as a military structure but later transformed into a noble residence.

[1][2] Over time, expansions included the addition of an extra floor to the west wing and the enhancement of the structure with frescoes above the main entrance and beneath the porch inside the courtyard.

From the 17th century onwards, the northern wing was adapted to include large halls with floral-decorated vaulted ceilings, which are now used for temporary exhibitions.

The architect Boggio di San Giorgio designed the elegant staircase leading to the first-floor corridor, characterized by large arched windows overlooking the surrounding countryside.

[1] Towards the end of the 19th century, the castle underwent a major restoration works under the direction of Alfredo d’Andrade and his collaborator Carlo Nigra.
