The Haute-Marne is a land of metallurgic tradition, traces of which can be found since 1067. Today, many of its companies are leaders in their sector of activity. GHM, in Sommevoire, perpetuates this long tradition in the field of cast iron art and urban furniture. Many cities are “dressed” by material made in Haute-Marne, such as the entrances of the Parisian Metropolitan, the lampposts of the Alexandre-III bridge or the Wallace fountains.
