The fort is accessible via a drawbridge, and its walls offer breathtaking views over the cliffs and the endless expanse of the sea. Between the towers, battlements, and cannons, history is palpable—and it's easy to understand why this place has often served as a film set, including "The Vikings" starring Kirk Douglas.

At the end of the coastal path from Cap Fréhel, Fort La Latte stands perched on a rock high above the sea. This impressive fortress has guarded the Emerald Coast since the 14th century. Originally built as a castle, it was later expanded into a coastal fortress to protect the Breton coast from attacks from the sea.

Originally known as the Château de la Roche Goyon, this majestic fortress sits on a narrow headland and offers breathtaking views of the Baye de la Fresnaye and the open sea. The path to the fort took me through a picturesque landscape blooming in all the colors of the heather. The coastal hike from Cap Fréhel to Fort la Latte was not only scenically beautiful, but also pleasant to manage. The fresh sea breeze and the view of the cliffs made the hike a special experience. The fort itself was a journey into the past. As soon as I entered, I felt like I had been transported back to the Middle Ages. The well-preserved complex and the lovingly restored historical accessories made the visit particularly exciting. I was lucky enough to take part in a short tour during which a guide in historical costume told exciting stories and facts about the fortress. From the top of the defensive tower, I had an impressive panoramic view of the entire complex and the surrounding coast. The climb was a bit strenuous, but the view made up for all the effort. The opportunity to stroll through the different parts of the castle and admire the details of the architecture was fascinating. It is advisable to come early, as the fort is well visited even in the off-season. Parking is free, and even with the camper van I found a shady spot. A public toilet area was also available, which made the stay even more pleasant.

Gilles van Bretagne lived here in the 15th century, a poet and womanizer who lived a merry life, hence the expression "courir le guilledou" (to go on a woman hunt). But his brother, Duke Francis I of Brittany, suspected Gilles of plotting and had him imprisoned. Because he didn't die fast enough, he was then strangled. Before his death, however, Gilles subjected his brother to divine judgment and the duke also died, tormented by remorse
