Fort-la-Latte is a medieval fortress located on the Cap Fréhel peninsula in the Brittany region of France. It was built in the 14th century to protect the coast from English attacks during the Hundred Years' War.

The fortress is surrounded by steep cliffs on three sides and has a drawbridge and portcullis at its entrance. It features several towers, including the main tower or keep, which offers panoramic views of the surrounding area. The fort has undergone several restorations over the centuries, but it retains much of its original architecture.

During the 17th and 18th centuries, Fort-la-Latte was used as a prison and later abandoned. It was rediscovered in the 19th century and restored by the French government in the early 20th century.

Today, Fort-la-Latte is a popular tourist attraction, offering visitors a glimpse into medieval life and architecture. It has been featured in several films, including "The Vikings" and "The Last Legion". It is also a popular spot for birdwatching, as it is situated in a nature reserve and offers stunning views of the Brittany coastline.
