This massive treehouse, located in Crossville, Tennessee, is thought to be the largest in the world. The 80-room structure is four stories high, 97 feet tall and is supported by six trees in all, the largest being an 80-foot-tall white oak. It was closed to the public due to being a fire hazard, but there are hopes that necessary changes will be made so that visitors may once again be allowed to enjoy the fanciful building. Via Uproxx
Sounds like so much fun to explore! Too bad it's closed to the public.
