A Marvel of Engineering

Coral Castle is a feat of engineering that I still cannot explain with my all sensors. Made entirely of coral blocks that were quarried, shaped, and moved by one man, Edward Leedskalnin, it is a mystery and marvel. The castle includes features like a sun dial, rocking chairs that weigh hundreds of pounds but can be easily moved, and a 9-ton gate that swivels on a pivot without any machinery. According to historical records, no one saw Leedskalnin using any equipment to move the blocks, and he worked on the castle at night. It is said that he had a secret knowledge of magnetism and leverage systems. The castle and the surrounding garden are also works of art, with carvings of hearts and planets, an unusual obelisk, and signs bearing cryptic messages. If this was a movie plot, I would think it exaggerated, but seeing it firsthand I still have no real explanation as it seems impossible.
