Tips from the Community
In 832, Conuvoion, a Breton monk, founded the Abbey of Saint-Sauveur in Redon with the support of the Carolingian Emperor Louis the Pious. A small rural community slowly grew up around the abbey. During the Middle Ages, the town benefited from its location on the Vilaine River, as trade goods could be transported upstream to Redon on ocean-going vessels. There, the goods were transshipped and transported further on inland waterway barges towards Rennes, the capital of Brittany. In the 19th century, Redon experienced another period of prosperity with the construction of the Nantes-Brest Canal. Even today, the old shipowners' houses and the large harbor basin bear witness to its history as a trading port.

Redon has managed to retain its quiet, small-town character, despite its intense activity (and traffic). Following the floods of 2024, the campsite is closed. The pedestrian street is pleasant and not overcrowded with shops. Just what you need. A visit to the port is also a pleasant experience.

The Story of François and Thérèse Mitaillé On August 7, 1944, in the final chaotic weeks of the German occupation, François Mitaillé and his younger sister Thérèse left their home in Penhap, a small hamlet near Marzan. They wanted to return to the farm to tend to the animals. On their way, they were stopped by German soldiers, taken away, and never seen alive again. Days passed, then weeks. The village lived between hope and fear. Finally, it was their own father who, after an endless search, found their bodies—tortured and shot. The loss was immeasurable, not only for their family, but for the entire community. The memorial commemorates François and Thérèse, brother and sister, who were torn away by the violence of war in the prime of their lives. It stands here as a silent witness and a warning that freedom can never be taken for granted.
