AquaDom at Radisson Blu Hotel Berlin
Take a swim with the fish while you ride the elevator in the atrium of the Radisson Blu Hotel in Berlin’s city centre. The impressive cylindrical glass lift provides 360-degree views of 1,500 aquatic residents, contained within the world’s largest free-standing aquarium. Measuring 25m (82ft) in height and 11.5m (37.7ft) in diameter, the cylinder holds 1m litres of salt water. The glass-floored lift travels at a speed of 0.30m (1ft) per second through the underwater world and can hold a maximum of 30 people.
