Fort la Latte, or the Castle of the Rock Goyon (, ), is a castle in the northeast of Brittany, about southeast of Cap Fréhel and about west of Saint-Malo, in the commune of Plévenon, Côtes-d'Armor. 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. It also features in the French band Manau's video for "La Tribu de Dana." A much larger, fictionalized version of the fort appears in the 2015 animated film April and the Extraordinary World. Historical The castle of the Roche Goyon has been classified as a monument historique by the French Ministry of Culture since 1925. 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. 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. It was in service until the end of the First Empire when the evolution of military techniques led to its unsuitability. From 1892, it was sold to various private owners before being bought by the historian Frédéric Joüon Des Longrais in 1931 who, having a lifelong passion for archeology, undertook heavy restoration work which took more than twenty years. Electricity only arrived at the castle in 2015. Location The fort can be found on a rocky cape, near Cap Fréhel, in the town of Plévenon. This site was chosen because of its favorable location - being difficult for an enemy to attack due to the lack of easy access and, in addition to it offering clear views of the English Channel the Emerald Coast and a large part of the Bay of St-Malo to provide warning of an approaching enemy, the cliffs on which it is built
