The St. Augustine Ripley's is located in Castle Warden, an historic Moorish Revival style mansion built in 1887. Built as a winter home for Millionaire William Warden, Castle Warden later served as a fashionable hotel owned by Norton Baskin and his wife, Pulitzer prize-winning novelist, Marjorie Kinnan Rawlings, author of The Yearling, Cross Creek and South Moon Under. Since 1950 the building has been the original permanent location of Ripley's Believe It or Not! Museum.
