The Tropical Islands indoor resort in Krausnick, Germany is located on the site of a former Soviet military air base.
The resort occupies a hangar built originally to house airships designed to haul long-distance cargo.
Tropical Islands opened to the public in 2004 and offers visitors a tropical getaway complete with exotic flora and fauna, a beach, lagoon, restaurants, water slide, evening shows, sauna, adventure park and overnights stays ranging from rudimentary to luxury.
The hangar is so big, the Statue of Liberty could stand inside it.
