A small, lesser-known museum in the Marolles.
For over 25 years, it has been defending the artists outside the classical cultural circuit, the outsiders, the self-taught or psychologically fragile.
The entrance costs only 4 euros. I heartily recommend their last expo, "Il était une fois l'art brut" ("Once upon a time, there was art brut"). The raw or outsider art is usually associated with the possible origins of art: the childhood, the primitive, the savage, the confinement.
Jean Dubuffet is considered the father of art brut. The nicest thing about this expo is the classification by colours, easy to grasp even by a child. So don't hesitate to spend an hour with your family in this charming museum...
Address: 312-314 rue Haute, 1000 Brussels
