The Collection de l’Art Brutin Lausanne is the first museum in the world dedicated to this art, created outside any school by self-taught creators, often on the margins of society, free from any need for recognition and from collective norms and values. Jean Dubuffet (1901-1985) is the inventor of the concept of Art Brut (raw or outsider art) and he assembled the first collection, starting in 1945, which he left to the city of Lausanne in 1971. There were then over 5,000 works by 133 creators, and it has since been extended by many acquisitions. Since 1976, this collection has been open to the public at the Château de Beaulieu in Lausanne. It is still the reference for marginal art. The museum offers a rich programme of exhibitions (about four per year) that allow the discovery of almost 700 works from the collection, year-round and over four floors. It also offers many activities for younger visitors who are particularly receptive to this playful art.
