Here's a modern version.
We invite you to tour our sculpture garden in stone, built by one man, Edward Leedskalnin. From 1923 to 1951, Ed single-handedly and secretly carved over 1,100 tons of coral rock, and his unknown process has created one of the world's most mysterious accomplishments. Open every day, the Coral Castle Museum welcomes visitors from around the world to explore this enchanting South Florida destination.
To this day, no one knows how Ed created the Coral Castle. Built under the cover of night and in secret, at a time when there were no modern construction conveniences, Ed would only say that he knew "the secret of the pyramids." When he died, his secrets died with him, and to this day scientists and thinkers still debate Ed's methods.
What makes Ed’s work remarkable is the fact that he was just over 5 feet tall and weighed only 100 pounds. In this part of Florida, the coral in some areas can be up to 4,000 feet thick. Incredibly, he cut and moved huge coral blocks using only hand tools. He had acquired some skills working in lumber camps and came from a family of stonemasons in Latvia. He drew on this knowledge and strength to cut and move these blocks.
In 1940, after the carvings were in place, Ed finished erecting the walls. The coral walls weigh 125 pounds per cubic foot. Each section of wall is 8 feet tall, 4 feet wide, 3 feet thick, and weighs more than 58 tons!
When questioned about how he moved the blocks of coral, Ed would only reply that he understood the laws of weight and leverage well.
