Hotels around the world each have their own fair share of grandiose features. One of the most impressive, though, is a giant aquarium. Expectedly enough, you’ll find some of the best looking ones in places which are located close to beaches or the ocean. Amazingly, though, there are also surprising gems to be found as well. If giant aquariums make your vacations complete, you don’t want to miss out on these hotel highlights.

Radisson Blu Hotel in Berlin, Germany

While most giant tanks are quadratic, the Radisson Blu’s aquarium is a graceful cylindrical structure and it’s considered to be the largest cylindrical aquarium in the world. It stands at 82 feet tall and has a generous 40 feet diameter. The aquarium also holds 264,172 gallons of water. This aquarium is called the AquaDom and could be found at the lobby of the hotel.
