AquaDom, the world’s largest cylindrical aquarium, is located atthe Radisson Blu Hotel in Berlin—just how tall is this breathtaking aquarium? 25 meters!

The Radisson Blu Hotel boasts a long history and a prime location. In addition to 427 guest rooms, Wi-Fi, a fitness center, a swimming pool, a sauna, and a steam room, it also offers 15 top-tier meeting rooms for business travelers. Thanks to its proximity to the Spree River, it’s just a five-minute walk to famous attractions such as Alexanderplatz and Hackescher Markt.

 

An elevator travels straight through the massive aquarium, with an observation terrace above offering spectacular views. Guests can also enjoy international cuisine and daily buffet breakfasts at the Heat restaurant right in front of the aquarium, watch fish “swimming in the sky,” or even go diving to feed them.

Beyond accommodation, this unique facility provides an experience that no other hotel can match!
