Coral Castle, previously named “Rock Gate”, was built single-handedly by Edward Leedskalnin (1887 - 1951) in South Florida, USA. It consists of numerous cut-out limestone rocks formed from coral, some weighing several tons. Its creation is surrounded by legends about how reverse magnetism causes levitation.

However, inventor Scott Russell (1961) from Burlington in the USA state of Vermont has reverse engineered and rebuilt the contraption that Ed Leedskalnin used to build Coral Castle. In the video from 2015 embedded below, he demonstrates that Leedskalnin could have used conventional devices to quarry, move, and put these massive blocks into place:

Does this mean that Edward Leedskalnin’s life work has now been demystified? No! Many people have built the Perpetual Motion Holder, as described in detail by Leedskalnin. Simply do your own search on the Internet, and you will find many videos showing the remarkable features of this device.

Edward Leedskalnin’s universal theory of the individual North and South pole magnet, named “Cosmic Force”, is described in his books:

• A Book in Every Home (a nature backed manifesto of philosophical musings offering for example political guidance, and parenting advice that includes a separate instruction highlighting the inevitable ramifications of inappropriate love making)
• Mineral, Vegetable and Animal Life
• The Above Reading
• Magnetic Current [PDF] (a detailed experimentation manual for researchers interested in learning how to become real scientists through direct experimentation and refined results interpretation methodology)
