Fort la Latte (Château de La Roche Goyon) — Attraction in Dinan

Fort la Latte, or the Castle of the Rock Goyon (French: La Roche-Goyon, Breton: Roc'h-Goueon), is a castle in the northeast of Brittany, about 4 kilometres (2.5 mi) southeast of Cap Fréhel and about 35 kilometres (22 mi) 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.

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 gave excellent protection from any attempted invasion from the sea.

Construction materials were easily accessible: with granite coming from the heart of Brittany, sandstone being directly recovered from the surrounding cliffs there are traces of old quarries on the coast, whose connection to the castle is revealed by toponyms such as "Port Taillé" which can be found on the cadastre and wood was in plentiful supply from the many forests which existed nearby in medieval times.

The fort was an important strategic point since it was not far from the trade routes connecting Saint-Malo, Normandy and the...

On July 31, 2025, we visited the impressive Château de la Roche Goyon, better known as Fort la Latte, located on the rugged coast of Plévenon in Brittany. Built around 1340, this medieval fortress sits dramatically atop a rocky cliff overlooking the Bay of Saint-Malo, near Cap Fréhel. The fort itself is a mighty structure made of grey-pink sandstone, complete with thick walls, sturdy towers, a portcullis, and even a furnace once used to heat cannonballs red-hot. Inside, you'll find old weapons and breathtaking views of the sea.

Admittedly, with an entrance fee of €31 (for 2 adults and 2 children), it's not the cheapest outing—and to be honest, you’ve seen most of it within an hour. That said, the fort is excellently preserved and has served as the backdrop for more than 20 films, which comes as...

It was very crowded. From the parking place you already have to put on a mask because of Covid-19. More then half of the people apparently can't read or understand an image of a masked face. Because they didn't wear a mask at all. This was one of the reasons we turned around at the gate. Also in the castle area, which we could see from a distance, very few people wore a mask. There is a small road to the left and right. But it's so small that keeping distance from others is hard. If you want to visit this place wait until after the pandemic or keep an eye on the charts of...
