Den Blå Planet, also known as the National Aquarium Denmark, is the largest aquarium in Northern Europe. Located in Kastrup, Tårnby, the facility is situated on a promontory extending into the Øresund strait. The building's distinctive whirlpool-inspired architecture was designed by the Danish firm 3XN and opened to the public in 2013, replacing the former Danmarks Akvarium in Charlottenlund.
The aquarium houses approximately 20,000 animals across 53 tanks, featuring a diverse range of marine and freshwater species. Its exhibits are organized into distinct sections, including the Amazon rainforest, the African Great Lakes, and the cold waters of the North Atlantic. A central feature is the 16-meter-long underwater tunnel, which allows visitors to observe sharks and rays from beneath the surface.
The project was initiated to replace the aging Danmarks Akvarium, which had operated in Charlottenlund since 1939. An architectural competition was held in 2008, won by 3XN, with the goal of creating a landmark building that reflected the marine environment.
Construction began in 2010 on a site reclaimed from the sea. The design features five 'arms' radiating from a central foyer, mimicking the shape of a whirlpool. The exterior is clad in over 33,000 diamond-shaped aluminum shingles that change color based on the sky and water conditions.
The aquarium was officially opened by Queen Margrethe II in March 2013. Since its opening, it has served as a major center for marine education, conservation, and public engagement in Northern Europe.
Den Blå Planet serves as a significant cultural and educational landmark in the Copenhagen metropolitan area. It plays a vital role in public outreach regarding marine biology and environmental conservation, bridging the gap between scientific research and public awareness. The building itself is considered a masterpiece of modern Danish architecture, frequently cited for its integration into the coastal landscape.
Scholarly debates and areas of uncertainty
Discussions surrounding the facility often focus on the ethical implications of keeping large marine predators in captivity versus the educational benefits provided to the public. Additionally, the environmental impact of the building's construction on the local Øresund marine ecosystem was a subject of study during the planning phase.
