The belfry of Mons is one of the more recent among the belfries of Belgium and France. It is classified as a World Heritage Site by UNESCO since 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.

They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
