The Musée d'Orsay, originally a train station designed by Victor Laloux in 1900, houses a huge collection spanning the period between 1848 and 1914, and is home to a profusion of works by Delacroix, Corot, Manet, Renoir, Pissarro, Gauguin, Monet, Caillebotte, Cézanne, Van Gogh, Toulouse-Lautrec and others.Alongside the Louvre and the Pompidou Centre, it's is a must-see in Paris, especially its famed upper levels, which have just undergone a serious brush-up. The top floor is still devoted to Impressionism, while you'll find Art Nouveau, decorative art, sculpture, Post and Neoimpressionism art, and Naturalism on the middle floors, including a section on Nabi.
On ground level, the school of Barbizon, realism sculpture before 1870 and symbolism take pride of place.
