Den Blå Planet (English: The Blue Planet) in Kastrup, a suburban area of Copenhagen, is the National Aquarium of Denmark and one of the largest structures of its kind in Europe. The aquarium is also renowned for the iconic, organic shape of its building.

Denmark’s Aquarium, the precursor of The Blue Planetwas opened to the public in 1939 in the town of Charlottenlund, in Copenhagen’s outskirts.
In the early 2000s, the old house of the aquarium proved to be too small and an international competition was organized in 2007 for the design of a new home in Kastrup, about 8 kilometers south of Denmark’s capital city.

Completed in 2013 after a design by Danish practice 3XN, the Blue Planet is a highly immersive scientific museum. The building of the aquarium is characterized by an imposing, yet elegant, shape inspired to that of a huge whirlpool. Here you can find more information on the Blue Planet’s architecture.

The permanent exhibition presents creatures from cold and warm sees – including many sharks and a reconstruction of a coral reef – and freshwaters.
Along with living animals and plants, the museum also features multimedia and interactive exhibits.
