This museum occupies the underground section of the building on Place du Musée and was laid out by the architects Bastin and Beek around a lightwell. The collections on display take the visitor on a journey through the artistic movements of the 19C (neo-Classicism, Romanticism, Impressionism) and 20C (Young Belgian Artists, COBRA, Surrealism etc) and include works by famous names (Jacques-Louis David, Fernand Khnopff, Gauguin, Bonnard, Rodin, James Ensor, Georges Segal, Francis Bacon, Delvaux…).
