The Musée de l'Orangerie reopened its doors to the public on 17 May 2006. The Musée de l'Orangerie permanently holds the Nymphéas by Claude Monet and the 144 paintings from the Jean Walter and Paul Guillaume collection featuring Cézanne, Renoir, le Douanier Rousseau, Matisse, Derain, Picasso, Modigliani, Soutine, Utrillo, and Marie Laurencin. With architects Firmin Bourgeois and Ludovico Visconti, the Orangerie was renovated in order to move the Nymphéas to the upper floor of the gallery. They are now available under direct diffused light as was originally intended by Monet.
