The AquaDom at the Radisson Blu hotel lobby was the world's biggest free-standing circular aquarium. The 14-meter-tall (46-foot) fish tank cost €12.8 million (about $13.6 million) to construct.

When you go inside, you will find a circular aquarium. This is the 360 degree panoramic water tank 'GURURI'. The appearance of jellyfish in the water tank of 'GURURI' is fantastic from the outside.
