Coral Castle in Homestead, Florida, is one of the most amazing structures ever built. In terms of accomplishment, it’s been compared to Stonehenge, ancient Greek temples, and even the great pyramids of Egypt. It is amazing – some even say miraculous – because it was quarried, fashioned, transported, and constructed by one man: Edward Leedskalnin, a 5-ft. tall, 100-lb. Latvian immigrant. Many men have single-handedly built their own homes, but Leedskalnin’s choice of building materials is what makes his undertaking so incredible. He used huge blocks of coral rock, some weighing as much as 30 tons, and somehow was able to move them and set them in place without assistance or the use of modern machinery. And therein lies the mystery. How did he do it?
