Porte de Sous-Murs walks

Langres is one of the sub-prefectures of Haute-Marne. The town is unique in being completely surrounded by ramparts, making it the town with the longest fortified wall in Europe. This section takes you on a tour of Langres’ historic centre and along the 3-kilometre-long walkway of the medieval fortifications. The route through the town itself is equally charming, featuring a number of historic monuments, including Saint-Mammès Cathedral, and for those wishing to extend their visit to Langres, there is also the town museum to explore.
