Canavese
Canavese was a region between Turin and the Graian Alps, centred on Ivrea. Its castles were divided among counts, while Ivrea was contested by its bishops, Montferrat and Savoy. In 1337 Bishop Palladio Avogadro held the see.
Amadeus VI, the Green Count of Savoy, took Ivrea in 1356 and built its brick castle the next year. Canavese later shared French and Spanish occupations of Piedmont before returning to Savoy in 1814.
