The Bourigan windmill is an old windmill that has lost its sails but is distinguished by its "large head" (a typical shape for a windmill with a massive body). It was heightened in the 20th century, giving it a unique profile. Although it is not open to the public, this windmill remains an emblematic vestige of Breton rural heritage, marking the region's milling history.

This old ruined mill is unfortunately not very visible due to the numerous weeds that hide the building.

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.
