Popular around Lac Du Gouet
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.

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