The Musée de l'Orangerie is most famous for being the permanent home for Claude Monet's Les Nymphéas (Water Lilies), but it also holds the Walter-Guillaume collection, including masterpieces of impressionist and post-impressionist part from Renoir to Picasso. It's located in the old orangery of the Tuileries Palace in the west corner of the Tuileries Gardens next to the Place de la Concorde.
