AN ELEVATOR IN A FISHTANK

An elevator in a fishtank? Why not.

The AquaDom in Berlin, Germany, is a 25 meter tall cylindrical acrylic glass aquarium with built-in transparent elevator. It is located at the Radisson SAS Hotel in Berlin-Mitte. The DomAquarée complex also contains a hotel, offices, a restaurant, and the aquarium's sea life center.

It cost about 12.8 million euros to construct. The acrylic glass cylinder was constructed by the U.S. company Reynolds Polymer Technology. The outside cylinder was manufactured on-site from four pieces and the inside cylinder for the elevator was delivered in one piece.

The Aquadom is the largest acrylic glass cylinder in the world, with a diameter of over 11 meters, built on a 9 meters tall concrete foundation. Filled with about 900,000 liters of seawater, it contains some 2600 fish of 56 species. The feeding of the fish and the cleaning of the fish tank is performed daily by a pair of full-time divers.
