Musée d'Art Classique de Mougins
This hidden gem "highlights the dialogue between the old and the new" with Roman, Greek, and Egyptian art rubbing shoulders with pieces by Picasso, Matisse, Cézanne, Warhol, and Dalí. Expect to come across a sarcophagus alongside a Cocteau or a Hirst sculpture next to an ancient bust. Spread over four floors, the museum also houses antique jewelry and the world's largest private armory collection.
