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 viaduct has spanned the Parfond de Gouet valley since 1904. Like many other engineering structures in this region, it was built by Harel de la Noe, the chief engineer of bridges and roads, for the departmental railway network. The Saint-Brieuc to Paimpol line operated until 1956. Today, bicycles have replaced the little train!

A path rather than a road that comes across a somewhat unexpected passage with a beautiful view from above.

The Greenway - and the Percée Viaduct - a fascinating story, which can be read on the information panels and is very interesting to me. Here's a translation of Vaduz: Like elegant young ladies striding over the valleys of the Lilliputian kingdom, at the beginning of the 20th century, nine viaducts, including the Parfond de Gouët Viaduct, with their beautiful brick arches, stretched along the very first railway line of the local network, St. Brieuc - Plouha. These engineering structures, built by a native of the region, Louis Harel de La Noë (1852-1931), a bridge and road engineer, allowed the small train of the Côtes-du-Nord to follow the winding and steep coastline without much effort. Lightness and elegance are the words that come to mind when describing the architecture of this 1903 building, characterized by numerous columns and arched vaults and its masonry in warm brick colors. The techniques used demonstrate boldness, ingenuity, and originality: reinforced concrete anchors (rebars) were installed to increase the compressive strength of the pillars and prevent cracks.

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.

The photo is not extraordinary, but the place is worth the detour. Lots of small paths or singles for lots of fun.
