  • The Comcast Building is the focal point of the entire Rockefeller Center complex.
  • The building looks dramatically different when viewing its narrow and wide facades. From 5th Avenue it is an elegant, narrow shaft while looking down 6th Avenue it forms an enormous slab.
  • The vertical and Gothic-inspired detailing of the austere Art Deco facade is integrated with a slim, functionally expressive form. Inside, this modern skyscraper features an open floor plan.
  • The lobby's rich materials and reduced black and beige ornamental scheme are enhanced by dramatic lighting.
  • Granite covers the base to a height of 1.2 meters (four feet), and the shaft has a refined facade of Indiana limestone with aluminum spandrel panels.
  • An escalator - a striking feature for its time - provides access to the shopping concourse below.
  • Nicknames include "The Slab" and "30 Rock".
  • The building was awarded landmark status in 1985.
  • Whilst under construction in 1932, this building is where the famous photo "Lunchtime Atop a Skyscraper" was taken by the photographer Charles C. Ebbets. The photo shows 11 construction workers eating whilst sitting on a steel beam seemingly suspended in mid-air.
  • The "Top of the Rock" rooftop observation deck closed in May 1986, and reopened on November 1, 2005. Its elevators have glass ceilings facing into illuminated shafts.
