The Arzal dam is built on the Vilaine estuary between Arzal and Camoël. It is the largest estuary dam in Europe. It is 500 meters long and has a sea wall and five gates. To allow circulation between the river and the ocean, the dam has a lock. A port is also located nearby.

The building dates from at least the 17th century and probably financed by Marie Quere of Benguë. Burnt down during the Revolution in 1793, it was partially rebuilt in 1817 by the rector Jacques Jouin. The chapel has a very beautiful white altar with statues of saints inside.

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.
