The belfry of Mons is one of the more recent among the belfries of Belgium and France. This belfry, classified in Belgium since 15 January 1936, belongs to the major cultural patrimony of Wallonia. and is classified as a World Heritage Site by UNESCO since 1 December 1999. It is the only one in Belgium that is constructed in baroque style. With an altitude of 87 meters, it dominates the city of Mons, which is constructed on a hill itself.
The building was designed by architecture Louis Ledoux. He led the works from 1662 until his death in 1667. The work was continued from 1667 to 1669 by Vincent Anthony. This belfry is both a prestigious construction and a functional building as it served to warn in case of fire or, during the Second World War, to give alerts against incoming bombardments.
The belfry of Mons does not have all possible belfry characteristics like the presence of a jail or rooms serving the Justice department, but the Hainaut province is not a region with belfries that are as typical as the ones in Belgian Flanders and in French Flanders.
It houses a carillon with 49 bells.
From the top of the building, the battlefield of the Battle of Mons can be observed, as well as the Borinage, the plains of the Haine and the hills and hillocks at the side of it, the cement factories and the terrils of the old coal mines of the "Levant of Mons" in Bray (Binche).
