the small town of kastrup in denmark celebrates the public opening of its newest aquarium designed by local practice 3XN. the ‘blue planet aquarium‘ is derived from the nautical swirl, a pattern repeated not only in the fluid behavior of water but throughout marine wildlife design as well, the radial shape also dictates the organization of spaces and circulation. the tentacle-like structure seems to hover over a reflecting pool, and once inside the visitor is immersed within several underwater ocean-scapes; similar to the function of a whirlpool, the project pulls the guest into the deep blue to observe the sea life.
