Derby Clock, Louisville. Recently moved to Fourth Street and re-dedicated, this handcrafted, 45ft clock was designed to look like a giant wind-up toy. The elevated five-lane racetrack features miniature caricatures of Kentucky celebrities as jockeys, including President Thomas Jefferson, Daniel Boone, George Rogers Clark and King Louis XVI, the city's namesake. The clock also features the Belle of Louisville, the oldest operating steamboat in America.
