There is no road on this viaduct, just a railway! Komoot won't suggest it to you anyway. The road passing at the foot is a fairly large country road but pleasant. When it is not cluttered with brambles, it is possible to take a pedestrian and cycle path bordering the road on the pond side when leaving Le Relecq Kerhuon, up to the first crossroads (direction Le Douvez, Landerneau).

Built in 1664!! A beautiful building with a magnificent gabled façade! Here is the translation of the information board: On the square stands the house of Duchess S. de Trampellan, named in honor of the Queen of France who came to Landerneau in 1505. This private building, built in 1664 to replace an older building, is characteristic of the 17th-century bourgeois architectural style in the town. This private building, built in 1664 to replace an older building, is characteristic of the 17th-century bourgeois architectural style in the town. It is also called the Maison de la Sénéchaussée, in reference to the courtroom that was located on the upper floor of the market halls that were located on the square and were destroyed in 1825. The originality of this residential building lies in the different designs of its two facades, one made of wood with bay windows, the other of Logonna stone. The building is a listed monument.

A great tobacco bar! They serve very good coffee. We sat outside in the square – opposite La Maison de la Duchesse Anne. A truly beautiful spot! The Smurfs are everywhere – it would be good if you don't forget to register for the Guinness World Records next time.
