Question: Which Tennessee city was home to the world’s largest treehouse before it burned down in 2019?

Answer: Crossville

The 97-foot-tall tree house and church were supported by an 80-foot-tall white oak with a 12-foot-diameter base, with six other oaks providing support. Built by Horace Burgess, a minister, the treehouse became an attraction that drew visitors from far and wide before it burned down in 2019.
