It's a truly wonderful experience when the lock is opened for the sailing ships. This exciting spectacle, as the road is closed, the drawbridge is raised, and the sailors enter and exit the lock, is not to be missed.

The Story of François and Thérèse Mitaillé On August 7, 1944, in the final chaotic weeks of the German occupation, François Mitaillé and his younger sister Thérèse left their home in Penhap, a small hamlet near Marzan. They wanted to return to the farm to tend to the animals. On their way, they were stopped by German soldiers, taken away, and never seen alive again. Days passed, then weeks. The village lived between hope and fear. Finally, it was their own father who, after an endless search, found their bodies—tortured and shot. The loss was immeasurable, not only for their family, but for the entire community. The memorial commemorates François and Thérèse, brother and sister, who were torn away by the violence of war in the prime of their lives. It stands here as a silent witness and a warning that freedom can never be taken for granted.

Milestone marking the boundary of the Abbey of Prières. Created between 1248 and 1252, it was located in Billiers, near the Pointe de Penlann. The abbey was largely destroyed during the Revolution. There are still a few buildings, the bell tower and a few milestones at the boundary of its domain. This milestone is the easiest to find: it is decorated with a Macle (heraldic symbol) and an Ermine (symbol of the Dukes of Brittany who founded the abbey).

The old town, a small town of character, offers numerous walks, winding through old streets into belvederes with beautiful views. We particularly recommend the Chemin du Ruicard, which wanders through picturesque streets, some with stairs, lined with houses from the 16th and 17th centuries. From this point, you can also enjoy the view of the port which is a place of heritage and traditions. The village also has cafes and restaurants that serve local dishes if you want to take a break. La Crêperie La Sarrasine and La Mie de la Roche are the most popular places in the city.
