Ripley's Believe It or Not! The Original Odditorium is at 19 San Marco Ave. The museum of oddities and curiosities opened here in 1950. Castle Warden, a Moorish Revival mansion built in 1887 for a Philadelphia industrialist and later operated as a hotel by Marjorie Kinnan Rawlings, now houses more than 800 exhibits, from shrunken heads and torture devices to life-size wax figures and unusual works of art. Of interest is the Space Oddities exhibit.
