There's this endless list that features all the Parisian museums you could possibly visit and although I'm far from being able to say I've visited them all, I'm pretty sure I've already picked a favorite. I'm referring to none other than Musée d'Orsay.
It's housed in the former Gare d'Orsay, a Beaux-Arts railway station built in the late 19th century, which served as the terminus for the railways of southwestern France until 1939, and is one of the largest museums in Europe.
Its permanent exhibitions showcase mainly French art, including paintings, sculptures, furniture, and photography. The second floor's graced with busts and sculptures carved by Rodin. It also exhibits the largest collection of impressionist and post-impressionist masterpieces in the world, by painters Monet, Manet, Degas, Renoir, Cézanne, Pissarro, Seurat, Sisley, Gauguin, and Van Gogh.
This last part of the collection is primarily displayed on the final fifth floor of the building. It's easily my most favorite place to visit. Many tourists had no idea it even existed since the third and fourth floors are accessible for visitors to the temporary exhibitions only. So, make sure not to miss this gem!
Here you can marvel at masterpieces like Van Gogh's magnificent Starry Night over the Rhône, The Church at Auvers and Self-Portrait, Monet's Poppies, Blue Water Lilies and The Rouen Cathedral, Degas' Little Dancer of Fourteen Years and The Ballet Class, Renoir's Dance at le Moulin de la Galette and Girls at the piano, Manet's Luncheon on the Grass.
This last floor's complemented by an enormous terrasse that overlooks Paris as well as the backside of the two gigantic clocks that hang right beneath the museum's roof. You can also sit and rest at the restaurant that operates here.
