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.

This is where the boats gather - when we were here, there were no boat owners around - high noon!

Great stop off for lunch… however, food outlets close between 13:00 - 14:00 or 15:00.

The Saint-Gobrien Church is one of the few Romanesque buildings in Brittany. Inside, you'll discover over 400 square meters of ancient frescoes, dating from the 12th to the 17th century. A stunning visit, combining spirituality and painted heritage.
