Mons: Baroque Capital of Hainaut
With 97,120 inhabitants (2025), Mons is the capital of Hainaut, located about 56 km southwest of Brussels. The centre carries postal code 7000. The municipality has eighteen sections, including Jemappes (11,110 inh.) and Cuesmes (10,055 inh.).
Districts and profile
Mons centre : Historic core dominated by the baroque belfry (UNESCO) and the Sainte-Waudru collegiate church, each year the stage of the Doudou (Ducasse). European Capital of Culture in 2015, the city hosts UMons.
Jemappes and Cuesmes : Populous sections inherited from the mining past of the Borinage, now being redeveloped.
Lock types encountered
The historic centre of Mons lines up mansion houses and old dwellings fitted with old lever locks and period doors. The collegiate church and listed buildings require heritage-appropriate interventions. The redevelopment of the Borinage mining past is reflected in former terraced working-class estates, while recent districts and student housing use European cylinders and multipoint locks.
