While in Denmark I was fortunate enough to travel to the Den Bla Planet, National Aquarium Denmark. I’ve been to many aquariums but this one was fantastic. Here’s a small sample of what Wikipedia has to say about the Blue Planet.
National Aquarium Denmark, Den Blå Planet (Danish: Den Blå Planet, Danmarks Akvarium) is a public aquarium in Denmark. The original aquarium was located in Charlottenlund, but this facility closed in 2012[1] and most of the animal collection was relocated to the new and much larger aquarium Den Blå Planet (lit.: The Blue Planet) in Kastrup, a suburb of Copenhagen.[1] The National Aquarium Denmark, Den Blå Planet opened to the public in March 2013 and is the largest aquarium in Northern Europe.
