This wonderful aquarium built at the end of 2003 in Berlin, in the atrium of "Radisson SAS Hotel" around transparent, panoramic elevator. This is made possible through the combined efforts of designers and builders of "International Concept Management, Inc.", who did design and common construction work and "Reynolds Polymer Technology", who realized the more complicated part of the project - cylindrical acrylic glass aquarium with 11m diameter and 25m height. Inner tube of the aquarium, where the elevator move, was manufactured and installed in a single piece and outdoor roller tank was collected on the site from the separate 4 pieces. The AquaDom built on a 9 meters tall concrete foundation which can bear a load of 900 000 liters of see water. A pair of divers undertakes daily cleaning and fish feeding activities for 2600 fishes of 56 different species. This gigantic aquarium is the largest acrylic glass cylinder in the world and one of the most visited sights of Berlin.
