First lump of coal mined in Petite-Rosselle
In June 1856, the first lump of coal was mined in Petite-Rosselle from the Saint-Charles pit, two kilometres from what would become the “Wendel headquarters”, and later the Explor Wendel Park.
After this discovery, Emile Vuillemin, a consultant engineer with the “Compagnie anonyme des mines de Stiring”, founded by Charles de Wendel and Georges Hainguerlot, suggested carrying out further drilling to the south in order to develop the operation, which was limited to the north by the border.
