Top Ranked by TripAdviosr and Yelp! A Top 10 Historic Hot Spot in South Florida! Ed Leedskalnin weighed a mere 100 pounds, stood just over 5 feet tall and single-handedly in secret carved over 1,100 tons of coral rock, building his amazing castle. Scientists, Engineers and Scholars are still baffled since its opening in 1923. Ed built the Coral Castle at night in secret, so there was no one to witness his technique; some have said he had supernatural powers. See a 9-ton gate, a Polaris telescope and a Sundial. The Coral Castle has been mentioned on many major networks, including: Telemundo, Univision,History Channel, Discover Channel, Travel Channel, BBC World, Good Morning America, In Search Of..., Ripley's, Believe It or Not, and You Asked For It! Billy Idol even wrote his hit song, "Sweet Sixteen" just for Coral Castle!
