Located in the heart of Brussels, the Art et marges museum, museum of outsider art, questions art and its borders. The museum’s collection was created in the mid-1980s by self-taught artists, artistic workshops for people with mental disabilities or in psychiatric settings. Nowadays it is composed of more than 4000 international artworks produced outside the frequented trails of art. The temporary exhibitions, at the rate of three a year, mix artists on both sides of the margin, questioning the boundaries of art and its definition.
