The Big Treehouse, Family treehouse attraction in Marshalltown, Iowa.
The Big Treehouse is a wooden structure built around a maple tree in Marshalltown, Iowa, featuring multiple levels and interior spaces for exploration. The construction includes staircases and platforms that guide visitors through different sections of the structure.
Construction began in 1983 when the founder started with wooden pallets beside a tree. The project grew over the years into an established attraction in the community.
The Discovery Channel featured the treehouse on Monster Nation Series Episode 35, highlighting its architectural design and construction methods.
