Aquarium Megastructure: Nausicaá

Inside Europe’s largest fish tank

Sharks, caimans, tropical fish, sea lions… With its 35,000 seas creatures, Nausicaá attracts 600,000 visitors each year. But today, the aquarium is writing a new page in its history by becoming Europe’s biggest aquarium.

To meet this challenge, the engineers had to build a giant tank, as large as four Olympic swimming pools, and to develop a unique water filtration system, a world first. Each stage of the construction was a technical feat, including welcoming more than 22,000 additional animals, and hammerhead sharks.

From the structure’s architecture to the logistics of breeding thousands of species and bringing in hundreds more from all over the world, this film takes us on an immersive journey into this exceptional project.
