1. Old airplane hangar becomes home to a tropical island resort
On the outside the old Soviet airplane hangar in Germany, south of Berlin, is exposed to the changing seasons and harsh winters. But take a step inside and you will be transformed to a Caribbean-esque tropical island. Opened in 2004, the Tropical Islands Resort has made its sunny home in the worlds largest freestanding building, set in the 360 metre long, 210 metre wide and 107 metre high space. The biggest indoor tropical pool complex and water pool is set with a beach, lagoon, rainforest, swimming pools, water slides, spa and several restaurants and bars. An artificial sun keeps the air temperature at 26 degrees Celsius, offering visitors 365 days of nonstop summer.
