In July 2022, the Saint-Dizier, Der et Blaise agglomeration community launched the Fonte Art pass, which allows visitors to visit three emblematic sites of the Haute-Marne metallurgy industry: Metallurgic Park, the Conservatory of Metallurgic Arts and the Paradis de Sommevoire. The Metallurgic Park interpretation centre in Dommartin-le-Franc perpetuates the foundry tradition that has been present in the Blaise valley since the 13th century. Several industrialists from the region who are partners of the park are exhibiting some of their creations in the garden, such as this contemporary steel structure made by the GHM foundry in Sommevoire.
