The Hyatt Regency Atlanta, located on Peachtree Street in downtown Atlanta, Georgia, is an award winning hotel which opened in 1967. The John C. Portman, Jr. designed building has influenced hotel design since. When it was first built in 1967, the Regency Hyatt House, as the hotel was originally called, instantly became one of the most recognized buildings in Atlanta, and its open-air 22-story atrium and revolving rooftop restaurant became a "must-see" attraction by Atlantans and tourists alike.
In 1971 the Ivy Tower (now called Radius Tower) was constructed, which was also designed by John Portman. It closely resembles his Westin Peachtree Plaza, which opened five years later. So similar are the two buildings that in 1981, the Tower doubled for the Peachtree Plaza in the film Sharky's Machine starring Burt Reynolds. Stuntman Dar Robinson dropped (67 m (220 ft) from the Tower, setting a record for the highest freefall (unrestrained) jump from a building in a film.
