The castle was built in the 14th century by the Lord of Matignon, Etienne III Gouÿon. The construction of the castle began in the 1340s, its keep dates from the years 1365-1370.
It is a famous tourist attraction of the bay of Saint-Malo and the Emerald Coast (France) Côte d'Émeraude. This impressive castle was built on a small piece of land at the Bay of the Fresnay in the 14th century. Various films have been shot at this site, including The Vikings (1958) by Richard Fleischer with Kirk Douglas and Tony Curtis. A much larger, fictionalized version of the fort appears in the 2015 animated film April and the Extraordinary World.
In 1379, following the return from exile of the Duke of Brittany Jean IV, the castle was besieged by Bertrand Du Guesclin. The castle was attacked and taken a second time during the Wars of Religion in the sixteenth century, this defeat marking a time of abandonment of the building. It was not until the 18th century, under Louis XIV, that the castle resumed its strategic interest and was bastioned.en.wikipedia.org
