The Church of One Tree was built in 1873 from a single redwood tree milled in Guerneville, California. The tree used to construct the Church stood 275 feet high and was 18 feet in diameter.

Ripley's "Believe It or Not!"

Robert Ripley, a native of Santa Rosa, wrote about the Church of One Tree - where his mother attended services, - as one of his earliest installments of "Believe It or Not!" In 1970, Ripley repurposed the Church of One Tree as the Ripley Memorial Museum which was stocked with curiosities and "Believe it or Not!" memorabilia for nearly 2 decades.
