Citigroup Center is a 42 story, 588-foot (180 m) skyscraper in Chicago, Illinois. Located at 500 W. Madison (between Clinton and Canal Streets), the structure was designed by the architecture firm Murphy/Jahn in a late modernist style. The building, previously named the Northwestern Atrium Center, was constructed between 1984 and 1987 on the air rights obtained by the destruction of the headhouse of the 1911 North Western Station. Citigroup Center contains retail shopping and offices, and is connected to the platforms of the Ogilvie Transportation Center (which unofficially continues to be called Northwestern Station) and thousands of Metra commuters use the facility every day.
On 8 December 2006 a man opened fire in a law office located on the 38th floor of the Citigroup Center. Four people, including the gunman, were killed. One person survived.
