The Monument du Traité de Verdun is easy to miss but historically significant — it marks the agreement signed in this city in 843 that divided the Carolingian Empire and effectively created France and Germany as separate political entities. The treaty's line of partition became, in the long run, the frontier whose disputes brought the 1916 battle to the same valley.
The bronze relief, installed for the centenary of the 1916 battle, shows the three grandsons of Charlemagne meeting at the moment of signing. It stands in the small park beside the Hôtel de Ville.
