Berlin has rightly earned a reputation as one of the world’s coolest cities – and perhaps that’s why it’s not that surprising that the German capital is also home to one of the world’s most impressive aquariums.

For truly stunning aquatic life and structures that house them you don’t have to head an educational institution – you can just visit the Radisson Blu Hotel. Built in 2004 as part of the Sea Life Center complex, the AquaDom (which was constructed at a cost of 12.8 million Euros) stands 82 feet high and holds more than 1,500 fish, 50 of which are unique species. This aquarium’s tower is so large (holding 260,000 gallons of water) that an entire team of divers has to clean it three to four times each day.

The entire Sea Life Center houses multiple aquatic exhibits and displays; an interactive rock pool where guests can physically interact with some of the aquarium’s gentler sea life, as well as a transparent tunnel that allows visitors to “walk through” and take in the fantastic creatures. But the clear star of the show is the freestanding cylindrical aquarium: an elevator shooting through the center of the aquarium affords guests dramatic. above ground views of underwater life.

Don’t take our word for it, though; check out the sights for yourself:

AquaDom Baby Ray

As of June 17th, 2015, there were five two and three month-old baby rays. Raised along with these rays in the “Kindergarten Aquarium” are a group of young cat sharks. Don’t let the image fool you; what appear to be eyes on the bottom of the rays are actually small gills. Source: Jens Kalaene/EPA
