  • Standing out among the flat-roofed prisms of midtown, Citigroup's pitched roof has become a powerful symbol of its namesake corporation.
  • Double-decker elevator cars reduce the area devoted to the vertical circulation core, leaving more space available for offices.
  • A computer driven load mass damper enables the reduced number of vertical supports and ensures the stability of this building.
  • The overhanging corners were designed after St. Peter's Lutheran Church, which occupied one corner, insisted on keeping its lot and its separate identity. A new church was however built in place of the old one.
  • The tower's base is cut away at the four corners, leaving it standing dramatically on a cross-shaped footing which extends from the core to the center of each side.
  • Plans for creating residential space on the upper floors were abandoned due to zoning restrictions.
  • The slanted crown is 160 feet tall, and was originally intended to hold solar power conversion panels.
  • The first skyscraper in the U.S. to be built with a tuned mass damper.
  • In order to correct the building's potential weakness in high winds, two-inch-thick steel plates were welded over each of the building's 200 bolted joints.
  • The atrium, open-air concourse and office tower lobby were renovated in 1997.
  • Citigroup Center was acquired by Boston Properties in 2001.
  • Citigroup Center is located at East 53rd Street and Lexington Avenue directly across from 599 Lexington Avenue, another Class A office tower in the portfolio of Boston Properties, Inc..
  • In 2004 the roof was reclad.
  • At one point the tower was considered capable of collapsing in a strong wind. When news came that a storm was coming to the city, emergency crews worked around the clock to reinforce the tower.
  • The architects were recognized with an Honor Award from the American Institute of Architects in 1979.
