The reconstruction is great! But we left some parts in ruins, which preserves the character of an old building.

This climb is often used by cycling races, particularly the Tour de France. A fairly long climb (2.2 km) with a very steep first section. Average gradient of 6.55% with a maximum of 15%. https://profils.cols-cyclisme.com/2811.svg

No tips, just enjoyed the solid Mairie building and the fine-looking bar-tabac nearby. Noyal-Pontivy is reached by some lovely, very quiet roads from Pontivy.

Well-known to Breton cyclists, the Côte de Mûr-de-Bretagne has become a classic of the Tour de France, with its characteristic straight climb. Although short, it can get your thighs burning with more than 500 meters at over 10% and a peak at over 13%.
