With over 10 centuries of history and on a huge rock, which monitors the jaudy estuary leading up to La Roche-Derrien. The castle-fortress here has thick walls leading down to the village. A stone arm almost hugging the town. It is a lively example of the history of Britanny during their civil wars of succession in the 14th and 15th centuries. Its streets are unmistakable with the view of the church of Sainte-Catherine, that lies on a hill near the city. A crossroads ... and overlapping stories that have made it one of the most bucolic towns in Britanny. It is a crossroads between the Armor Coast (Côte d'Armor) and Argoat, which were areas of great commercial influence on the way to the Channel Islands.
