Facts

  • Two towers similar to this one were planned for the lots on either side. Both sites are reserved for future development, and the northwest plot is a temporary park.
  • The front lobby is a large two-level winter garden with glazed palm trees and an 86-foot high glass roof.
  • World's tallest reinforced concrete building when completed; surpassed two years later by Central Plaza in Hong Kong.
  • Raymond Kaskey's bronze sculpture "Gem of the Lakes" looks over the winter garden from the Wacker entrance. It depicts a large Neptunian figure drying himself over a seashell fountain.
  • The lower level of the winter garden was designed to connect via underground passageway to Union Station.
  • 311 South Wacker Drive is the tallest building in the world known only by its street address.
  • The canopy over the sidewalk in front of the winter garden was added to the building in 2002.
  • The lantern at the top changes colors for various holidays and special events.
  • The building's top is a large cylinder surrounded by four smaller cylinders. One prototype design included four spires around the circumference.
  • The five cylinders on top are lit at night by 1,852 fluorescent tubes, creating a light bright enough to compete with the full moon.
