One Prudential Plaza
Structure in general
- When the Prudential Building was finished it had the highest roof in Chicago. Only the statue of Ceres on the Board of Trade rose higher.
- This was the first high-rise office building completed in Chicago since the LaSalle Bank Building in 1934.
- Underneath the building is the Randolph Street terminal of the Metra Electric Line commuter railroad, serving the south side and south suburbs.
- By 1956 the observation deck had already attracted a million visitors.
- The building had a public observation deck until a new generation of much taller skyscrapers made it obsolete.
- Initial design schemes called for two symmetrically placed side masses at the lower floors; instead the western bustle was eliminated and the eastern one heightened to open the building towards Michigan Avenue.
- The facade is made of vertical strips of limestone and ridged aluminum.
- When it opened the building included one of the largest parking facilities built within an office building in the world.
- Upon completion in 1955, the tower featured the world's fastest elevators.
- One Prudential Plaza was built above and beyond office standards of the day and won numerous industry awards for its design.
- The wall next to the main entrance shows a relief carving of the Rock of Gibraltar, the symbol of the Prudential Insurance Company designed by Alfonzo Ianelli.
