This is one of the most mind-blowing stories of all time...Coral Castle, Ed Leedskalnin's enigmatic monument of human (and some would say, supernatural) achievement. At five feet tall and 100 pounds, Ed built a Castle out of the ground, using only the most basic of tools, moved gigantic rocks weighing several tons by himself and nobody ever witnessed him at work, as he worked secretively under the cover of night. It's still a mystery how he did it. Ed claimed to have discovered the secrets of the pyramids. Whatever his secret was, he carried it to the grave with him and to this day, scientists and engineers are mystified by his achievments.
