CORE CRUSH: THE BIG BLUE
The Radisson Blu hotel in Berlin seems like a pretty normal hotel from the outside. But step inside and you will be blown away by what has to be one the most remarkable hotel features: the world’s largest cylindrical aquarium with one million liters of saltwater. A stunning habitat for many species of tropical fish. The AquaDom is maintained by the Sea Life Berlin, which is located right next to the hotel.
Guests can take the two-story elevator ride through the middle of the AquaDom, during which they will learn all about both the tropical fish inhabitants.
