The gallo-roman fortification of the "Mont Vireux"
Excavated from 1979 to 1990 by Jean-Pierre Léman, the Mont-Vireux is covered by a fortification set around 260 A.D., during the reign of the Gallic emperor Posthume (260-269). This one reorganised the defense of the Northern Gaul, in respond to the German intrusions. The site was then used sporadically with a destruction phase around 350. The last quarter of the IVth century shows German influences, clear in the neropolis 500 m away from the site, and so certainly the existence of German troops on the Mont-Vireux. Various occupations still occurred during the Middle Age till the XVth century.
The site is open access. Guided tours are also offered.
