5. Heritage USA
This Christian theme park, water park, and residential complex was built in Fort Mill, South Carolina and comprised 2,300 acres. It operated from 1978-1989 and was the brainchild of PTL televangelist Jim Bakker and his then-wife, the late Tammy Faye Bakker Messner. (As a side note, much of the park was built by noted church builder Roe Messner, who later married Tammy Faye after she divorced Jim.)
At its height, this vacation destination earned $126 million per year and was on par with Disneyland and Walt Disney World. But when it was revealed that Bakker had been having an affair with Jessica Hahn, and he also got a federal indictment for fraud, attendance dropped. The IRS revoked the park’s tax exemption status, and then in September 1989 Hurricane Hugo hit and caused lots of damage. It closed after that. Since then, much of the park has been sold and redeveloped.
