Very little information exists about this area before 832; however, it would seem that there was a parish by the name of Riedones which gave the town its name. In 832,
Conwoïon, a
Breton monk with the help of the
Carolingian Emperor
Louis the Pious founded the
abbey of Saint-Sauveur de Redon. Today, documents relating to life within the abbey still exist. The town developed around the abbey until a small rural community of 6,000 inhabitants was formed in the 1960s. In the Middle Ages, Redon benefitted from maritime commerce due to its location on the Vilaine. ==Population==
