(Aulnoy-lez-Valenciennes, Bantouzelle, Briastre, Noyelles-sur-Selle and Potelle use the same arms.)

The Lamour Watermill, Briastre (French: Le Moulin Lamour) is a museum and art center located in the commune.

Preponderantly operating the mechanical processes of milling (grinding), rolling, or hammering up until the 1930s, the watermill was converted into a museum by the Bellevals in the late 1990s.
