This Visite Apero is retained because the source anchors the walk in the history of Arc-en-Barrois: the Aujon river, forest resources, forges, blast furnaces, sawmills and local trades. It also names figures linked to the town, from Jean I and the Duc de Vitry to Etienne Bouchu and Aurelie Picard. The event is more than an aperitif visit; it is a guided reading of how water, forest and industry shaped a small Haute-Marne community.
