The history of the Danish Aquarium began on Christmas Eve 1934 with the dream of the Danish zoologist Mogens Hoygaard to build greenhouses for amphibians and fish. The dream was supported by his father and part-time engineer Knud Hoygaard, and only five years later in 1939 the second largest aquarium in Europe opened in Copenhagen. The first aquarium building was in Charlottenlund Park.
In the first month of work, more than 77,000 people visited the first Danish public aquarium. The ventilation was not designed for such attendance and several guests even lost consciousness from stuffiness. Over the next fifty years, under the direction of Mogens Hoigaard, the aquarium was repeatedly reconstructed and completed, along with the collection of marine inhabitants. By the mid-nineties, it became clear that the buildings in Charlottenlund were too cramped and outdated for modern aquarium collections. In 2007, an architectural competition was announced for the best project of the Blue Planet modern aquarium, in which 38 architectural companies took part. The Danish company 3XN won the project, and in March 2013 a new aquarium building was opened - an elegant structure made of metal and concrete, which seems to float above the water.
Today, the Blue Planet Aquarium offers its visitors a collection of 20,000 marine inhabitants in 53 aquariums with a total volume of 7 million liters, located on the territory of about fifteen thousand square meters. Aquariums are divided into zones, from arctic waters to the tropics. Each aquarium has a display, some of them are interactive, you can turn on the backlight in the aquarium. For children, a small area is equipped where you can touch the mollusks and sea urchins. And in the open area with exits from the cafeteria and the aquarium, you can enjoy a cup of coffee, sea air and watch the fur seals that are fed by the aquarium staff.
