Thanks to its natural recources like water, timber and iron ore but also sand, the Haute-Marne has developed extensive metallurgical industries. Among the best known achievements are the Fountains of Wallace, which decorate the small squares of Paris, the majestic statues who dominate the principal cities of the department and the "Art Nouveau" ironwork by Guimard which decorates the balconies of Saint-Dizier. The entrances to the parisian metro and the ornate street lights of the Champs-Elysées also come from here.
