Pushing the Bounds of Sanity

After he was left by his fiance the night before their wedding, Ed Leedskalnin spent 28 years constructing the Coral Castle in secrecy, mostly at night, as a monument to his bride no more. He managed to move 1,100 tons of coral with nothing more than hand tools. The Coral Castle is so weird and wonderful that Billy Idol wrote his 1986 hit "Sweet Sixteen" as a tribute to it. In 1984, the castle was added to the National Register of Historic Places. Located in Miami, it is now a museum listed under its original name, "Rock Gate Park." (www.coralcastle.com)
