Canavese, with its extraordinary variety of landscapes, is a show-piece of the Turin province. Ivrea is the chief town of this territory. The city is surrounded by a Morainic Amphitheatre formed during the great Ice Age. The withdrawal of the Balteo glacier gave way to the morainic ridge of the Serra di Ivrea and numerous lakes, such as the five lakes of Ivrea, lake of Candia, and lake of Viverone. Green valleys and gentle hills extend throughout the area of Canavese, which is rich in natural, historic and artistic treasures. Valchiusella, which divides the province of Turin from Valle d’Aosta, is particularly striking. The entire valley is an extraordinary testimony to the presence of the legendary Salassi and, later, of the Roman populations.
