From 1905 to 1948, the train made a stop there between Saint-Brieuc and Moncontour. The inhabitants of the Grèves used it frequently to get around and transport goods, particularly bricks produced by the nearby factory. It was called the "Petit train des Côtes-du-Nord", the former name of the department, because there was only 1 m spacing between its rails compared to 1.435 m on a normal track.

Classified as a Nature Reserve since 1998, all this wild nature almost disappeared during the 20th century. A landfill was located a little higher up, and plans for a port or even an airport were circulating. After twenty long years of fighting, led in particular by naturalists and local residents, the bottom of the Baie de Saint-Brieuc has regained its original calm and serenity. This landscape of water channels surrounding salt meadows, completely covered during the high tides, welcomes a diversity of birds from all horizons every year.

Majestic arched viaduct, it is part of the many works of art in the Bay of Saint-Brieuc built by engineer Harel de la Noë at the beginning of the 20th century. 10 m high and 58 m long, it spans a small stream, which once allowed the Chemins de fer des Côtes-du-Nord line to connect Saint-Brieuc to Moncontour.

Located on the tip of Illemont, it is an ingenious way to observe the birds of the Nature Reserve without being seen. On the right, the Grève de Saint-Guimond and its network, with its ducks and barnacle geese. Just opposite, on the other bank of the Bay, the site of La Cage (commune of Langueux) is one of the main sites for wading birds: sandpipers, oystercatchers and curlews in particular. On the left, the Fontreven grasslands form a refuge area for little egrets, brant geese and many other birds. https://www.baiedesaintbrieuc.com/sit/observatoire-ornithologique-pointe-dillemont-hillion/ Photo credit: Emmanuel Berthier
