Side view, The National Aquarium of Denmark

The National Aquarium Denmark, Den Blå Planet is Northern Europe’s largest aquarium with thousands of animals and seven million liters of water. The building’s architecture, created by 3XN architects, was inspired by the circulating currents of the whirlpool. From the entrance, the visitor steps into the vortex of the whirlpool – the round lobby – and is drawn inside the spiral towards the 53 aquariums and installations.
