Found by accident ! Tiny place whose name I cannot recall, but was pretty full of locals enjoying a meal and chat when I stumbled in abou 1300 on a Mon. You can enjoy a plat du jour with coffee afterwards for about 12,50 EUR, and wine/cidre seem inexpensive. In and out in <20 mins if that is your choice or linger longer if you prefer.

Beautifully done street sculpture. Why not position one of your friends in the peloton and grab a photo of them riding with Anquetil et al?

At an altitude of 184 m, the Glomel trench is the highest point of the Nantes-Brest canal and the watershed between the Blavet and Aulne basins. The canal project and its passage through the center of Brittany dates back to Vauban, the decision and the route to Napoleon. The impressive trench allows the Aulne and Blavet watersheds to communicate via the canal. The Grande Trenche of the Canal from Nantes to Brest was dug in the 19th century by deserters from the army of Louis XVIII. The 4000 convicts of Glomel had to move as much earth and rock as was necessary for the construction of a great pyramid in Egypt. It took 9 years to create this trench, more than 3 kilometers long, 100 meters wide and 23 meters deep.

Carhaix-Plouguer (/kaʁɛ pluɡɛʁ/Note 1), commonly called Carhaix, is known to be one of the most flourishing cities of Gallo-Roman Armorica during Antiquity, then bearing the name Vorgium (Latin name of the capital of the Gallic and then Gallo-Roman people of the Osismes). It is today known for hosting, since 1992, the Vieilles Charrues festival, one of the main music festivals in Europe.

On this square in La Tour-d’Auvergne in Carhaix, the convent of the Hospitallers once stood. The Notre-Dame des Grâces chapel, located near the Post Office, is the last vestige. Victim in 1875 of a fire which almost destroyed it, the hospital was definitively abandoned in 1920 and its ruins were completely leveled. Probably used as a fairground since the Middle Ages, this ancient square adjoined the moat of the Carhaix castle. It was in 1841 that the bronze statue executed by the sculptor Charles Marochetti of Théophile Malo Corret de La-Tour-d'Auvergne was erected. This place was also called Martroy or Martret, a term which means market in old French. It therefore logically had to fulfill this function. Logical, given its location in the city.
