The Sainte Marie Coal Mine is one of the major Ronchamp coal mines, located in Bourlémont (Ronchamp, Haute-Saône), in eastern France. It was worked intermittently between 1866 and 1958, then finally closed. The concrete headframe was reinforced in 1924 by Charles Tournay. This Liège engineer and architect specialized in constructing concrete headframes. On 29 March 2001, the headframe was listed as a French national monument historique.^[2]
