Discovery of the medieval castle. From the XIIth century the keep of an incredible originality, well deceives its world: behind its smooth and proud walls is revealed the beautiful carved decoration of a Romanesque room topped with a dome. Upstairs, the twelve radiant niches decorated with grimacing foliage and heads support the twelve stone ribs that support a dome vault with a central oculus. The historic room offers an overview of the history of the site and the remains discovered during the excavations. The Renaissance apartment will reveal its fresco if you take the time to observe. And during your stroll in the rooms you can admire the various exhibitions proposed. Do not forget the terrace and its panoramic view of the valley and the Lure mountain.
