Each Ripley Odditorium is approximately 10,000–20,000 square feet in size and features 400–700 exhibits. The bizarre, the disturbing, and the beautiful are all carefully balanced. The Odditoriums contain works of art created from found objects, remarkable collections, and odd hobbies.
The Ripley collection ranges from microscopic sculptures that are unseen to the naked eye to 22-foot tall automobile part robots and massive dinosaur bones. From prehistoric to futuristic, the Ripley collection of over 25,000 items has it all, including the world's biggest repository of the famed Robert Ripley's personal papers. His diaries, passports, significant contracts, and thousands of pages of personal correspondence are all part of the Ripley Entertainment collection, which is world-famous.
