From Youtube: "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."
