In 1931 when the Chrysler Building opened, you could go up to the 71st floor observatory (in the spire) and take in views of the city from all four sides for $0.50. The celestial-themed observation deck closed down in 1945 and according to Moses Gates in his book Hidden Citiesit’s now occupied by a private firm.
