*The Verrerie Royale de Saint-Louis, located in the French commune of Saint-Louis-lès-Bitche in Moselle, is the oldest crystal factory in France (1586). In 1829, the glassworks became the Compagnie des Cristalleries de Saint Louis. The crystal factory, still in operation today, was bought in 1989 by the famous luxury house Hermès. Saint-Louis is, after Baccarat, the largest French crystal manufacturer.
