The Musée d'Orsay is a museum in Paris, France, on the Left Bank of the Seine. It is housed in the former Gare d'Orsay, a Beaux-Arts railway station built between 1898 and 1900. The museum holds mainly French art dating from 1848 to 1914, including paintings, sculptures, furniture, and photography. It houses the largest collection of Impressionist and post-Impressionist masterpieces in the world, by painters including Berthe Morisot, Claude Monet, Édouard Manet, Degas, Renoir, Cézanne, Seurat, Sisley, Gauguin, and van Gogh. Many of these works were held at the Galerie nationale du Jeu de Paume prior to the museum's opening in 1986. It is one of the largest art museums in Europe.
