Musée National Gustave Moreau

This is one of those special museums where far from the massive scope of the grand institutions, you are immersed in the concentrated universe of a single artist. In the double-height studio, there are paintings literally all over the walls, and shutters containing hundreds more drawings and watercolours, so you can really see the ideas and preparation that went into Moreau's work, and his fetish subjects like Oedipus and the Sphinx, Salome, winged and clawed beasts and fantastical architectures. Down below is the cluttered apartment Moreau shared with his parents, symbolically arranged by the artist himself with drawings and mementoes. It's also an intriguing sort of artwork in itself, symbolically arranged by the artist with the idea of a museum in mind.
