Since its opening in December 2003, the AquaDom has become a centerpiece of the Radisson SAS Hotel Berlin in Germany. Filled with more than 250,000 gallons (over 940,000 L) of saltwater, the aquarium is host to 56 species of fish (2,600 fish total).
Hotel visitors can ride a crystal clear elevator through the core of the 52 foot (15.85m) tall cylindrical aquarium and dine at one of the restaurants atop the aquarium. Two full-time SCUBA divers are responsible for the daily care and cleaning of the fish, coral, and acrylic panels.
This groundbreaking aquarium is the first of its kind and the Guinness Book of World Records named it the largest cylindrical aquarium in the world.
The aquarium required 41 R-Cast™ acrylic panels – 26 panels for the outside cylinder and 15 panels for the inside – and 16 on-site bonds in order to create the 36 foot (11.08m) diameter aquarium. Adding to the engineering complexity, the base of the AquaDom is elevated 29 feet (8.84m) above the ground.
The outside of the aquarium was assembled in four pieces in the hotel. The elevator core arrived on-site fully assembled.
