The AquaDom is a massive aquarium located inside the Sea Life Center under a Radisson Blu hotel in Berlin. It has a diameter of 36 feet, and the foundation is 30 feet tall. The aquarium is 82 feet high and holds over 260,000 gallons of water. The AquaDom is the largest acrylic cylindrical aquarium in the world by volume. A glass elevator runs up and down right through the center of the tank.
The AquaDom is home to 1,500 fish from 97 species. Visitors can watch as the fish in the aquarium are given 18 pounds of food every day at 2 p.m. The aquarium needs to be cleaned by divers three or four times a day.
The AquaDom was built by Union Investment Real Estate GmbH. The acrylic cylinder for the aquarium was constructed by International Concept Management, Inc., an American company. Twelve sets of panels for the outside cylinder were sent from the factory and assembled on-site. To make the inside cylinder, three sections of five panels each were bonded together near the hotel. The tank cost about 12.8 million euros to construct. It was completed in 2004.
Several other water attractions are located under the AquaDom, including a walk-through underwater tunnel and an interactive rock pool. The DomAquaree complex also includes a hotel, offices, a restaurant, and the Sea Life Center aquarium.
