Fort la Latte or Castle of La Latte is a castle in the northeast of Brittany, about 4 kilometres southeast of Cap Fréhel and about 35 kilometres west of Saint-Malo, in the commune of Plévenon, Côtes-d'Armor.
It is a famous tourist attraction on the Cote d'Émeraude. This impressive castle was built on a small piece of land at the Baie de la Fresnaye in the 13th century. Various films have been shot at this site, including The Vikings 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.
The castle has been classified as a monument historique by the French Ministry of Culture since 1925.
