There’s plenty of competition, but this may be Florida’s strangest attraction. In 1923, the story goes, a 26-year-old Latvian crazed by being dumped at the altar by a 16-year-old (I hate when that happens), moved here, to what was then the boonies. He spent the next quarter century carving huge boulders into a Flintstones-like roofless “castle,” now on the National Register of Historic Places. It seems impossible that one rather scrawny little dude could have done all this, but there are scores of affidavits on display from neighbors swearing to it. Experts have apparently studied Ed Leedskalnin’s methods to help figure out how the great pyramids and Stonehenge were built. Rocker Billy Idol was said to have been inspired by this place when he wrote “Sweet 16.” An interesting 25-minute audio tour guides you through. Although overpriced and under-maintained, Coral Castle’s worth a visit if you’re in the area (likely en route to or from the Keys), about 37 miles from Miami.
