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.

With the patronage of "John the Baptist", this parish has chosen a saint who is considered a forerunner of Jesus Christ. In Christian theology, he is the voice of the voice in the desert prophesied in the Old Testament book of Isaiah: "A voice calls out: In the desert prepare the way for the Lord, make straight in the desert a highway for our God!" (Luther Bible). John is the son of Zechariah and Elizabeth, who was visited by the Mother of God Mary when she learned from the Archangel Gabriel that she herself was to give birth to Jesus Christ, and her - until then childless - relative was still pregnant in old age. The feast day of Saint Jean Baptist in the calendar of saints is June 24th.

Observation cabins allow you to stay on the lookout for wild life and enjoy a well-guarded world.

It is here that the Gouédic passes under the splendid Toupin viaduct. This work from the beginning of the 20th century, named after its architect, was built for railway use. A few decades later, when the car became the main means of transport, the viaduct was transformed and largely made ugly. In 2013, a restoration campaign made the viaduct an architectural jewel. It was included the following year on the list of historic monuments.
