Former Baly-Collard foundry

The Blay-Collard foundry was founded in 1882 by Gabriel Blay to produce malleable iron. Taken over in 1906 by his wife Marie Collard under the name Fonderie Veuve Blay-Collard, the factory was requisitioned by the German army during the First World War, and its equipment was taken away. Activity resumed in 1920, and the foundry became Blay et Laurent in 1922 under the management of Pierre Lucien Blay and Edmond Laurent. A family business for a long time, it evolved into Ardennes Fonderies, specialising in malleable cast iron. In 1962-63, the site was taken over by Gillet Roquigny, a hardware manufacturer, before ceasing production in 1978. Today, E.A.I. carries out anodising on the site.

The original foundry hall (1882) features Dom-le-Mesnil limestone walls, an asbestos cement long-sloped roof and semi-circular arched windows. A brick extension with exposed metal framework, built in the 1920s and 1930s, completes the ensemble. The offices, rebuilt as an extension to the hall, and three concrete block buildings for the anodising baths date from the 1960s.
