Narrow strip of land that juts out into the sea and offers wonderful views of the ocean.

A place of worship since the 8th century, this 12th-century chapel was destroyed by German occupants in 1944 and then rebuilt identically in 1949.

Unfortunately, the rock arch is no longer there. We also couldn't find a playground.

According to local legend, this rock was split in two by a lightning bolt hurled by the devil himself, furious at having been tricked by a sailor from Piriac. Others say it's a petrified ship, punished for braving the storms. A magical haven, where every wave seems to whisper these ancient tales!

The Devil's Table, with its strangely shaped rocks and Breton legends, is a must-see on the coastal paths of Piriac.

A symbol of the French naval defeat against the British off Dumet Island. A lost anchor, a destroyed fleet: this maritime tragedy sealed the decline of French power at sea during the Seven Years' War.

It was a small fishing port for sardines and anchovies in the 19th century. The sardine factory that we pass along to join the coastal path is the only witness of this period, today transformed into Apartments. The small port of Lérat is a natural site developed quite typical of Brittany. Today, the port of Lérat is a pretty little marina with 94 moorings with a superb beach of fine sand.
