Coral Castle is an oolite limestone structure created by the Latvian American eccentric Edward Leedskalnin.
The structure, located in Leisure City - Florida, comprises numerous stones (mostly coral limestone), each weighing several tons.
Currently a privately operated tourist attraction, Coral Castle is noted for legends surrounding its creation that claim...
it was built single-handedly by Leedskalnin using reverse magnetism or supernatural abilities to move and carve the numerous stones.
Edward spent more than 28 years building the Coral Castle, refusing to allow anyone to view him while he worked.
A few teenagers claimed to have witnessed his work, reporting that he had caused the blocks of coral to move like hydrogen balloons.
The only tool that Leedskalnin spoke of using was a "perpetual motion holder".
When asked how it was achieved he explained :"It's very simple if you know how. I know the secrets of the people who built the pyramids. "
