With more than 250 tools and machines dedicated to foundry and forging, the Conservatory of Metallurgical Arts is a tribute to the furnaces of the Haute-Marne department. It extends in an old foundry from the 13th century located in Dommartin-le-Franc. The site experienced significant expansion of its activities in the 18th century and has now become a museum. It aims to transmit the history and know-how of the region's metallurgists to the younger generations.
