The entire complex, including the castle and the surrounding small village, is certainly unique. Its proximity to the beautiful beach makes it a perfect destination for families.

A castle worth visiting, which was last expanded in the 15th century and has been restored since the 1960s. Children under 10 get in free and the 12€ per adult is not too much. There are also regular special events in and around the castle.

The chateau is actually a private mansion built in place of the original chateau. In the direction of Marle there is a beautiful garden in front of the castle.

Built at the end of the Middle Ages, Suscinio Castle was the residence of the Dukes of Brittany, part of the tradition of the great ducal residences then emerging in Brittany under the leadership of powerful dukes. It is located in the heart of what was once a vast wooded area, and which is today a collection of salt marshes and meadows.
