Coral Castle, Homestead, FL
Made from 1,100 tons of limestone boulders—bigger than those at Stonehenge—this structure, located just south of Miami, was built from 1923 to 1951 by a single man, a tiny Latvian immigrant named Edward Leedskalnin, as his home and an homage to the love of his life who left him the night before their wedding.
Mystery: How did he do it? The jilted man claimed he knew the secret to the pyramids’ construction. Other details—no mortar, precise seams, physics-defying balancing acts—have also stumped scientists for decades.
