Denmark's Aquarium is an aquarium in Denmark. The original aquarium was located in Charlottenlund, but this facility closed in 2012. The new Denmark's Aquarium with about 7,000,000 litres (1,500,000 imp gal; 1,800,000 US gal) of water, including a 4,000,000-litre (880,000 imp gal; 1,100,000 US gal) tank for sharks and rays, opened in March 2013 in Kastrup, a suburb of Copenhagen close to the airport.
Denmark's Aquarium in Charlottenlund started construction in 1937 and was opened in 1939. In 1974, this aquarium was expanded to feature five large landscape aquaria and a biological museum with theme-based exhibits and aquariums. In 1990, the facility was further expanded by a new front hall, café, improved toilet facilities and a schooler service. In the final years before the closure of the aquarium in Charlottenlund, it had about 1,000,000 litres (220,000 imp gal; 260,000 US gal) of water in about 70 aquarium tanks.
The main purpose of the aquarium is to disseminate marine information, help science projects, and help improve educational institutions.
