Homestead, Florida. 30 miles south of Miami. This former agricultural town is home to one of the most mysterious structures in North America, a stone garden made of sculpted blocks of ancient coral, some weighing 30 tons. It’s called the Coral Castle. Spread over several acres, the complex formations and intricate designs of the stone walls and sculptures marvel tourists. But unlike other great structures around the world, this site is not ancient.

“Coral Castle in Florida is often said to be the only modern megalithic structure ever built.”

David Childress (Author, Technology of the Gods)

In 1923, Ed Leedskalnin, a Latvian immigrant, began building what he originally called Rock Gate Park. But believe it or not, Leedskalnin insisted that he was not using modern machinery to build the impressive structure. He also claimed that he was working alone.

“Well, Ed was a hermit and Ed was a loner and he was a foreigner and he was a recluse and a scientist.”

Rusty McClure (Author, Coral Castle)

“He was in love with a woman, and he wanted to build this facility in memory of her. And he waited for her to come from Europe, and he waited and he waited, and she never did. But the big question is, is how did this frail little man move these thousands of pounds of block by himself.”

   – George Noory (Radio Host, Coast to Coast AM)

Barely over five feet tall and weighing just 100 pounds, Leedskalnin is said to have carved, moved and hoisted huge multi-ton stones using only a makeshift tripod.

“He has a tripod, three pieces of Florida Pine and he’s got some chains, and he’s now gonna lift 30 tons, ten tons of rock can’t be done. No one could do that.”

   – Rusty McClure (Author, Coral Castle)

“He would work at night he wouldn’t let anybody watch him. And he said that he knew the secrets of the pyramids.”

George Noory (Radio Host, Coast to Coast AM)

But what exactly was Leedskalnin referring to? Had he rediscovered the same advanced technology used to build megalithic structures like Carnac and Gobekli Tepe?

“Ed over and over again would tell people that he knew the secrets that helped the Egyptians build the pyramids. What was he talking about? Why was he constantly harking back to the Egyptians? We don’t know.”

Rusty McClure (Author, Coral Castle)

Leedskalnin continued work on the Coral Castle until his death in 1951. In the journals he left behind, the builder explained that he had discovered the ancient secret of transforming stones into weightless objects.

“Ed says this in his pamphlet, Magnetic Current, that real gravity is actually real magnet. So, if you reverse the magnet forces with a force of some kind of electromagnetic radio, perhaps, frequency, you can then make these rocks not as heavy as they seem otherwise and therefore you can lift them.”

 – Rusty McClure (Author, Coral Castle)

But if Leedskalnin had developed a device that could modify gravity, what was his secret? Some suggest the answer lies in a mysterious black box that can be seen in various photographs, a box that has since disappeared.

“The black box sitting on top is the element that no one has ever seen except in those pictures, and no one has today. We believe that black box has something to do with how he got these massive, heavy, brittle pieces of rock up in the air in a way that no one can duplicate.”

Rusty McClure (Author, Coral Castle)

“He had some kind of magnetic machine down in one of his other house areas that has since been dismantled, but it had a revolving ability. He may have been having that thing spin. The whole place could have been antigravity. He probably just pushed these into place.”

George Noory (Radio Host, Coast to Coast AM)

“Levitation is the only way that I know of to hold up very heavy objects. Very, very high-speed trains are magnetically levitated. These high-speed trains don’t have wheels that touch any tracks. They’re literally suspended above the track using magnetic forces.”

Sara Seager, Ph.D. (Prof. of Planetary Sciences, MIT)

“We can speculate at this time that there are techniques for using electromagnetism to nullify gravity. This was the great quest of Einstein. The motivation for such technology is, of course, to lift a large spaceship out into space and across space.”

John Brandenburg, Ph.D.
(Plasma Physicist, Orbital Technologies),
(Author, Life and Death on Mars)

Could it be that Ed Leedskalnin utilized antigravity to levitate and distribute the enormous rocks used to build Coral Castle? If so, where did this incredible knowledge come from?

“And he died, taking this secret to his grave. The question is, did he invent it, or did he himself somehow inherit it or learn it from a tradition or maybe from some visitor from another realm?”

– Philip Coppens
(Author, The Ancient Alien Question),
(The Lost Civilization Enigma)

“The only thing that is explainable is that someone with a higher form of physics and understanding of gravity has created the ability of one person to lift stones that modern technology could not do, the way he did it. It had to come from a different place in this galaxy.”

Rusty McClure (Author, Coral Castle)

“The fact that one guy created these massive structures is absolutely fascinating. Am I suggesting that he did this with extraterrestrial technology? No, because I don’t know. Am I excluding that possibility? No.”

– Giorgio A. Tsoukalos
(Publisher, Legendary Times Magazine)

If aliens visited Earth in ancient times, perhaps the world’s mysterious stone structures can provide clues not only to mankind’s past but to its future.

“I think that extraterrestrials would not have left our solar system some thousands of years ago without any proof. They wanted that in the far future we start to reflect, ‘Have we been visited by outer space?’”

Erich von Däniken (Author, Chariots of the Gods?)

Could additional evidence still lie hidden right before our eyes? Evidence that, when found, will prove once and for all that we are not alone?
