Interesting mystical facts: Ley Lines connect every F1 race circuit on the planet. If you draw a straight line around the Earth so that it exactly passes through two opposing corners of the great pyramid 'Cheops' you will disect the planet precisely into two equal halves.
Indeed, Edward Leedskalnin did spend over twent-five years constructing his Coral Castle. However, he did it at night and largely unobserved. His claim that he used no modern construction equipment (modern for the 1920's and 30's that is) was supported by his explanation that he knew the secrets of the Egyptians and how they built their pyramids. Of course, how the Egyptian pyramids were built is no longer a secret and only those in absolute denial continue to dispute theevidence and facts.
Don't take it from me, here's a nice way of putting it (if a little unkind to some 'believers'):
"There is one detail that virtually all agree on: since the reclusive Leedskalnin spent nearly thirty years working mostly at night and away from prying eyes, no one actually saw him move the coral. Since no one saw the blocks actually being moved, no one can state for certain that the task was accomplished by Leedskalnin alone. The claim that Leedskalnin didn't use modern (post-1920s) tools is obviously true, but the mistake is in assuming that modern tools are required to move the large blocks of coral.
Ultimately—and ironically—the solution may lie in Leedskalnin's own simple explanation: that he did it using principles of weight and leverage. "I have discovered the secrets of the pyramids," he said, employing the same methods used by ancient Egyptians. If Leedskalnin was being truthful, then the mystery is solved, for the methods by which the Egyptian pyramids could be constructed are well understood (see, for example, Mark Lehner's 1997 book The Complete Pyramids).
Photos exist of large tripods, pulleys, and winches at the Coral Castle site, and several sources (e.g., Wallace Wallington's Web site http://www.theforgottentechnology.com) demonstrate how massive weights can be moved by one or two people using simple physics. (The comparisons to Egypt's pyramids are a red herring; there are vast differences in weight, material, and complexity between the castle's coral slabs and the huge stone pyramids at Giza. Because coral is porous, large blocks appear heavier than they actually are.)
Many mystery mongers arrogantly assume that those living in earlier times (such as Leedskalnin, or the ancient Egyptians) were not clever or resourceful enough to possibly have created impressive engineering feats without extraterrestial aid or mysterious powers. This view betrays an ignorance of history and sadly underestimates human ingenuity. It seems likely that if scientists haven't explained the Coral Castle specifically, it's because there's little to "explain." The Coral Castle mystery seems to be simply a matter of poorly-informed people who reject a mundane reality in favor of a fanciful myth."
