Rennes-Carhaix road Segment 9
Mûr-de-Bretagne – Gouarec
This segment crosses a rugged territory but is often still viable today.
From the Square Saint Suzanne at Mûr-de-Bretagne take the road to Farm Kerguichardet and you reach downtown the holiday camp of Argoat where the roman road plunges into Lake Guerlédan. It remerges on the other bank approximately 600 meters away.
Where the lake stands today, there was a marshy valley fed by three streams which after a steep gorge, merge into the River le Blavet. In roman times, the path of the road, regularly-oriented E.N.E.- W.S.W, has undergone a bend South to cross the pond after the confluence of the three streams.
On the opposite bank the path is still passable (except for some stretches) until the Cross of Kergoff where it meets the modern road.
There it meets (8th intersection) another old path which, according to R. Kerviler (k04 – Kerviler) used to link Erquy(Reginea) to Vannes. This route passes to the North by Saint-Gilles-Vieux-Marché and South by Perret. As a confirmation of this description, substructures of an ancient bridge have been found close to the crossing of the River le Blavet at the old Abbey Bon Repos.
After le Zelò, upset by the new road RN 164, the original lay out leads us to the crossing of the River Daoulas immediately above the pittoresque gorges carved out by the river. This part is followed by the northern side of the hill that laps the River le Blavet until Rosquelfen.
This stretch, straight from the Farm Canac’h-Léron to the Farm Lan Uvelan, is particularly striking because protected by high vegetation. On the hill there are megalithic remains and at the highest point (m 255) construction and piping artifacts have been found like a sort of a fort of sighting.
