Inside Europe's Largest Aquarium - Nausicaa's Epic Engineering Feat

Dive into the epic story behind Nausicaa, Europe’s largest aquarium, and discover how this French marvel broke records with its 2.6-million-gallon tank and giant bay window!

In this captivating documentary, journey to Boulogne-sur-Mer to witness the transformation of Nausicaa, France’s National Sea Center, as it takes on an unprecedented challenge: doubling in size to become one of the world’s top five aquariums. Follow the relentless teams as they engineer a 2.6-million-gallon tank - the equivalent of four Olympic swimming pools - and install Europe’s biggest bay window, crafted from cutting-edge methacrylate to withstand 500 tons of water pressure. See how over 100 companies worked together to move 50,000 tons of rubble, lay 459,000 cubic feet of concrete, and design a complex water filtration system, all while racing against the clock to meet a two-year deadline.

Go behind the scenes with marine biologists and engineers as they breed 10,000 corals, acclimate endangered hammerhead sharks, and ensure the health of 60,000 sea creatures through innovative feeding and filtration systems. Learn how biomimicry inspired the aquarium’s unique architecture, and how Nausicaa’s expansion cements its place as a leader in ocean preservation and marine education. Whether you’re fascinated by mega-engineering, ocean life, or conservation, this video unveils every challenge and triumph of building Europe’s most ambitious aquarium.
