Near the parish church, you cannot miss the castle complex, consisting of a square tower (12th century) and a more recent main building (15th century) with exquisite cross windows.
The castle was once the residence of the powerful D’Avise family and only in 1645 did it go to the de Blonay brothers, who changed its name. The ancient towers was known as “des Prisons”: in 1787 the nobleman Philip de Blonay claimed joint rights with other lords in Avise to imprison wrong-doers. The tower was sold to local families by the Bianco family of San Secondo, while the annexed building was taken away from the Blonay.
