Berlin, Germany. A lift rising through the hollow centre of a cylindrical, 82-foot tall aquarium transports visitors through a full panorama of tropical sea life. Fish festooned with vibrant colours nibble at the aquarium wall inches from their human admirers. Almost a hundred different species, including blow fish, silver moonfish, and humphead wrasse, are represented in the tank, which holds over a million litres of water and is the largest cylindrical tank aquarium in the world. The ride is decidedly leisurely — perfect for revealing in the sensation of floating in an underwater wonderland.

The mesmerising AquaDom is situated inside a Radisson Blu hotel in Berlin, as part of Sea Life Berlin.
