Built-in elevator~~The world's largest aquarium: AquaDom

AquaDom was built way back in 2003, located inside the Radisson SAS hotel in Berlin, Germany. I'm sure many of you are already familiar with this giant, but there are probably even more people who have no idea about it.

This thing is touted as the world's largest aquarium, costing 12 million euros, and can be filled with 900,000 liters of saltwater in one go. Over 2,600 fish plus two divers coexist peacefully inside. The key point is that AquaDom stands at a height of 25 meters, requiring an elevator to fully take in its appearance.
