Building and structure collapses in Germany

12th-century accident in the Holy Roman Empire

The AquaDom (mixed Latin and German: 'water dome', more formally 'water cathedral') was a cylindrical acrylic glass aquarium with built-in transparent elevator inside the lobby of the Radisson Collection Hotel in the DomAquarée complex at Karl-Liebknecht-Straße in Berlin-Mitte, Germany. The DomAquarée complex also contained offices, a museum, a restaurant, and the Berlin Sea Life Centre aquarium.
