Symbolist painter Gustave Moreau was a contemporary of the Impressionists, but he worked against the grain, rejecting realism and naturalism to draw inspiration from the Bible, Greek mythology, Leonardo da Vinci, and Indian miniatures. This quaint museum, set in the elegant town house where he once lived and worked, has atmospheric period rooms that reveal Moreau’s obsession for Second Empire and Restoration-era knickknacks and furniture, and galleries filled with his fabulous mythical beasts and fantasy worlds. It’s a little-known gem.
