What you see above was the world’s largest airship hanger, located 40 miles south of Berlin, Germany. It was also the world’s largest free-standing building. Now, the same building has been put to a better use. Check out the new Tropical Islands Resort, a colossal water park with an integrated rain forest!
“But what a pool: At 3,000 square yards, it’s larger than four Olympic-size pools, and its artificial horizon conjures a faraway island. At the “shoreline” are 600 feet of sandy beach and hundreds of deck chairs. The Bali Lagoon has a grotto and waterfall, as well as the world’s largest indoor rainforest, with 50,000 trees in 600 varieties—from palm to papaya—that thrive in natural light. Its most popular attraction is a nine-story waterslide that propels sliders to 44 mph.”
