From this point, you have a superb view of the Josselin castle. There are opportunities for free and guided tours. The annual closure is from November 1 to April 8. The Castle dates from the beginning of the 11th century, when the nearby Viscount of Porhoët had a palisade built on this rocky promontory overlooking the Oust valley. In 1370, Olivier de Clisson, constable of France, had the fortress built.

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.
