Surrounded by 3.5km of ramparts flanked by 12 towers, Langres awaits for the walker from the top of its landscaped plateau, occupied since ancient Gaul.

Considered as a masterpiece of military architecture, the protected heritage that bears witness to the different periods is no less interesting. The successive eras, gallo-Roman, medieval, Renaissance, all have contributed to forging the city like it can be admired today.
