“It’s quite possible that the rumor about Juan Ponce de Leon desperately setting off in search of the Fountain of Youth was a deliberate insult to his memory or was intended to insult the powerful de Leon family, since the fountain stories don’t start showing up until several decades after Juan Ponce de Leon’s death,” said Carlton Hammel, a Florida resident who’s devoted the last 13 years to researching the Fountain of Youth story.

Not only do we not know how Leedskalnin managed to build the castle, but we aren’t even sure why he did it.

The official story, as told by Leedskalnin, is that he was rebuffed by his young sweetheart. When his beloved, Agnes Scuffs, refused to marry him, Leedskalnin salved his wounds by building the castle as a tribute to her and the life they might have had together.

The unofficial story, as also told by Leedskalnin (though not at all as widely as his tale of unrequited love), is that the castle was built as a temple to the Egyptian gods, constructed using the same techniques the ancient Egyptians used to build pyramids.

And later on he up and moved the whole thing ten miles up the road, without anybody seeing how he moved the massive several ton blocks of coral.

One guy has a theory about magnetic energy channels covering the earth (some people call them ley lines, i believe):

“I believe Ed discovered a way to move massive blocks of coral by taking advantage of the magnetic powers of the Earth,” said Ramirez. “The Earth is surrounded by an invisible web of energy that is concentrated at certain spots. At these spots energy flows freely and people are much stronger than they would be elsewhere.”

Anyway, Coral Castle is fantastically interesting. I want to visit sometime. There’s also a series of pamphlets that Leedskalnin wrote which detail his methods and theory, but apparently no one is able to really decipher the whole thing.
