Oceanographic Museum
The Oceanographic Museum represents Monaco's commitment to the marine environment. It houses the collections of Prince Albert I, the Scientist Prince, whose numerous cruises and research provided the basis of modern oceanography. The collections on show represent a complete range of marine and submarine fauna, with gigantic skeletons of oceanic mammals. The Musée houses what is probably the best aquarium in Europe, with nearly 4,000 fish from 350 different species occupying 90 seawater tanks. If you're unlucky enough to hit Monaco on one of those 65 rainy days, this is the perfect place to console yourself.
