Discovered anti gravity solutions and singlehandedly designed and constructed a multi ton coral/stone castle complex, so called “Coral Castle”. The only tool that Leedskalnin spoke of using was a "perpetual motion holder" So his amazing castle may hold clues to long lost powers and was compared to places like Stonehenge and the great Egyptian pyramids. What is most remarkable about the contents of the Coral Castle is the massive size of the stones and bricks used throughout the construction, all the more remarkable when one considers that one man assembled the entire site using only primitive tools.
