Chevalement du puits Sainte Marie, Mining headframe monument in Ronchamp, France.

The Sainte-Marie shaft headframe is a reinforced-concrete hoist tower built in 1924 by engineer Charles Tournay. Four vertical pillars carry the winding-wheel platform, whose axis stands 18.50 m high, with wheels 3.30 m in diameter. The lower building has concrete beams filled with brick and a four-sided roof; two legs brace toward the extraction machine. A steel stairway climbs to the tower.

The Sainte-Marie shaft was dug from 1864 to 1866 at the foot of the Bourlémont hill and served as a ventilation shaft until 1896, then lay abandoned. In 1924 the Ronchamp collieries reopened it as an extraction site and Charles Tournay built the reinforced-concrete headframe, though the Chanois shaft was preferred for coal. The pit closed in 1958; the headframe was restored in 1979 and inscribed as a monument historique on 29 March 2001.

The shaft takes its name from Saint Mary, a religious reference common among Ronchamp's pits, such as Notre-Dame and Saint-Joseph. Since 1994 the site has been decorated with a mine locomotive and wagons, and it is now a stop on the Ronchamp mining heritage trail linked to the Marcel Maulini museum.

The site is reached from Rue de la Chapelle and sits within Ronchamp's former mining area. Since it is an outdoor installation, comfortable walking shoes and weather-appropriate clothing are recommended for your visit.

The headframe survived demolition only through protests by local residents and the efforts of former mining doctor Marcel Maulini, who saw it as a relic worth keeping. In 1972 it was sold by EDF to the Haute-Saône departmental council for a symbolic one franc.
