The Oceanographic Museum (Musée océanographique) in Monaco-Ville, Monaco, is a renowned institution dedicated to marine sciences. Inaugurated in 1910 by Prince Albert I, the museum is part of the Institut océanographique, committed to sharing ocean knowledge. The museum was directed by the famous explorer Jacques-Yves Cousteau from 1957 to 1988. The museum houses a vast collection of sea fauna, including starfish, seahorses, turtles, jellyfish, crabs, lobsters, rays, sharks, sea urchins, sea cucumbers, eels, cuttlefish, and more. It also showcases sea-related objects, model ships, sea animal skeletons, tools, weapons, and a collection of material culture and ritual objects. The first floor is dedicated to the work of Prince Albert I, including his research yacht's laboratory. The museum's basement hosts an aquarium with 4,000 species of fish and over 200 families of invertebrates, presenting Mediterranean and tropical marine ecosystems. The museum also features artworks from various artists like Damien Hirst and Philippe Pasqua. The building itself is a stunning example of Baroque Revival architecture, towering over the cliff face to a height of 279 feet. The façade bears the names of twenty oceanographic research vessels, inscribed during construction. A visit to the Oceanographic Museum offers a deep dive into the fascinating world of marine life, ocean research, and maritime history.
