Douvenant Viaduct

Highlight • Monument

Built between 1903 and 1905, the curved Douvenant viaduct overlooks the valley of the same name.
131 meters long and 23 meters high, it allowed the “petit train des Côtes du Nord” to connect Saint-Brieuc and Langueux in the direction of Moncontour.
Rehabilitated in 2022, it reopened to gentle traffic and offers walkers and cyclists an exceptional view of the Bay of Saint-Brieuc.

Saint John the Baptist Church

Highlight • Other

The church presents a Latin cross plan with a three-aisle nave of three bays preceded by a fore-nave, a bell tower at the transept crossing, and a choir with side aisles of three bays with a flat chevet. The church has preserved from the 11th century the upper part of the nave walls: you can clearly see the small windows blocked to the north and south, above the large arches.

Saint-Brieuc Bay Visitor Centre

Highlight • Rest Area

The site is exceptional because it is located in the Nature Reserve which is home to a very varied fauna and flora. It can accommodate up to 40,000 migratory birds in winter. The site is also remarkable because it is located in the heart of the bay of Saint-Brieuc, the fifth bay in the world for the amplitude of its tides. The sea can recede more than 7 km! It is this natural heritage that the Maison de la Baie, classified as Maison Nature, lets you discover through its museum, its temporary exhibitions, its educational activities, its walks and its nature outings. Actions that show the richness of biodiversity, raise awareness of environmental protection and develop eco-citizen behavior.

The seabed of Saint-Brieuc Bay

Highlight • Other

The fifth bay in the world for the amplitude of its tides is located on the Channel-Atlantic migration axis. Between 30,000 and 40,000 birds make a migratory stopover here or reside there for the winter: Siberian geese, spotted locusts, Balearic shearwaters, skylarks, melodious linnets, brent geese... These guests know that in this landscape of more than a thousand hectares, apparently desert, intense animal life animates the waters and sand. A real pantry! The bottom of the bay is also home to remarkable geology, dunes, salt meadows...
