The history of the castle is closely tied to the temporal authority of the
Bishops of Ivrea, under whose control it remained since ancient times. In the year 1000, it was granted as a fief by emperor
Otto I to the Bishop of Ivrea, likely formalising an arrangement that had already in place for centuries. In 1326, the castle was granted to
Philip I of Piedmont, progenitor of the House of Savoy-Achaea, but was returned to the Bishop of Ivrea in 1361 following the wars in the
Canavese region. Rebuilt by bishop Bonifacio Ferrero after suffering from pillaging and decay, it was destroyed again during the
Piedmontese Civil War in 1641, being reconstructed in its present form at the beginning of the 19th century. The castle has served for centuries served as the summer residence of the Bishop of Ivrea, who to this day retains the title of Count of Albiano, though no longer in use. In 1841, it hosted
Ferdinando of Savoy, 1st Duke of Genoa. == References ==
