Carousel Columbia

Columbia Carousel or Carousel Columbia are a pair of double-decker carousels at Six Flags Great America in Gurnee, Illinois and California's Great America in Santa Clara, California. Both parks were originally built by the Marriott hotel chain as sister properties but they were later sold off and are presently owned by Six Flags and Cedar Fair, respectively. To this date, Carousel Columbia (the California counterpart) is the world's tallest carousel.
