Perched dramatically on a sheer cliff 85 metres above the Mediterranean, the Monaco Oceanographic Museum is one of the most iconic landmarks in the Principality. Overlooking the sparkling coastline, the museum combines architectural grandeur with cutting-edge marine science, making it one of the most visited oceanographic institutions in Europe. Known as the “Temple of the Sea,” the Monaco Oceanographic Museum offers an immersive journey into the wonders of the underwater world, all within an extraordinary setting in the heart of Monaco.
Founded in 1910 by Prince Albert I of Monaco — a pioneer of modern oceanography — the Monaco Oceanographic Museum has long been dedicated to marine research, conservation and education. Today, it occupies more than 6,500 square metres of exhibition space, blending historic collections with interactive displays and state-of-the-art aquariums. Its mission remains clear: to inspire visitors to better understand, protect and preserve the oceans.
Inside the Monaco Oceanographic Museum, visitors discover a spectacular series of aquariums showcasing more than 350 species of fish and over 6,000 marine specimens. From vibrant coral reef ecosystems to the mysterious depths of the Mediterranean, the museum presents a fascinating cross-section of global marine life. Rare and endangered species are carefully displayed in habitats designed to replicate natural conditions, offering both beauty and scientific insight. Sharks, seahorses, tropical fish and delicate invertebrates captivate visitors of all ages, while informative panels explain the environmental challenges facing the world’s oceans.
Beyond the aquariums, the Monaco Oceanographic Museum features extensive exhibition galleries dedicated to marine exploration and conservation.
