The Château de Josselin is a two-faced building whose architectural details tell a thousand-year-old story. Standing on a rocky outcrop, it overlooks the Oust valley. On the river side, an austere facade evokes the feudal struggles of the Middle Ages. On the courtyard side, a more refined sculpted granite facade offers a particularly well-preserved example of Breton architecture from the end of the 15th century and the beginning of the 16th century.
