Have you heard of the Coral Castle?
It's in Florida. Evidently some dude, 5 ft tall and 100 pounds, built a stone castle and gardens. By himself.
The stones weigh several tons, and fit together precisely. He claimed to use the secrets of the pyramid-builders of Egypt, Peru, and the Yucatan.
It's postulated that he used magnetism, reverse gravity, and/or sound to lift the stones into the air and into place.
