ed worked entirely alone and mainley at night, no one ever witnessed the construction of the castle. when questioned about his methods ed ( who was 5 foot and weighed in at 100 pounds)would explain he was very familiar with the laws of weight and leverage. however. ed's library contained a number of books on egyptology and magnetism which has led many folk to the conclusion that there may have been a whole lot more than leverage at play in the creation of the coral castle.
ed published 5 pamphlets during his life,and they are available at the gift shop for folks whose finances are in better shape than mine.>
