God told Horace Burgess to build a treehouse and that he did, the world’s biggest to be exact. The Minister’s Treehouse is located near Crossville, Tennessee and measures around 100-feet tall. The treehouse and church were an ongoing building project that spanned 14 years. The 10-story structure was built without blueprints around a living white oak tree and uses at least six other trees for support. Kristin Sweeting’s photographs of the treehouse are truly stunning.
