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.

Saint-Guimont Fountain and Washhouse

Highlight • Monument

The fountain-washhouse of Saint-Guimont was built in 1926 at the time of M° Provost, mayor of the commune of Hillion, like those of Saint-René and Juiguihen. Legend has it that Saint-Guimont would have landed in this strike, south of the tip of the Palus to evangelize this "peninsula". The fountain and the washhouse with its enclosure have recently been carefully restored by the municipality. In 1857, Mr. Brizeux, shipowner, requested a concession in the cove of the three fountains of Saint-Guimont, in order to develop a deposit of limestone sands and a shelter for the boats that the petitioner armed, to fetch sand shellfish in bay.

Ponts-Neufs Viaduct

Highlight (Segment) • Bridge

This old viaduct and footbridge, which spans the Gouessant river, dates from 1913, built by Louis Auguste Harel de La Noë for the Côtes-du-Nord railways.

The eight arches of the bridge were restored in 2004, and you can now cross it on foot and by bicycle.
