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.

In the 19th and 20th centuries, La Grève des Courses was a festive place where horse races and aviation meetings took place. However, it later became a wild dump where waste was thrown directly onto the sand, polluting the bay. Thanks to the efforts of environmental associations, it was transformed into a nature reserve.
