The Arc de Triomphe, Rue Foch, Montpellier, Languedoc-Roussillon, France, Europe It is more than 300 years old, that is to say, almost double that of Paris, and their Occitan pride leads them to try to bug the capitalists whenever they have the opportunity. At the back of the Peyrou we find another Roman-style monument built at the same time but much more impressive, Les Arceaux. It is a huge aqueduct made in the image and likeness of the Pont du Gard.
