Famous for its very rich impressionist and post-impressionist collections, and bathed in the smooth sunlight that passes through the glass vaulted-ceiling, the Orsay Museum offers to travelers the once-in-a-lifetime experience of admiring world-renowned works of art by the most acclaimed European masters. The Musee d'Orsay is, hands-down, one of the world's richest and most exciting museums. Its permanent collection houses countless great works by masters of early modern and impressionist art, including Matisse, Monet, Degas, Van Gogh, and Rodin.
