The Tribune Tower is a neo-Gothic skyscraper located at 435 North Michigan Avenue in Chicago, Illinois, United States. Built between 1923 and 1925, the international design competition for the tower became an historic event in 20th century architecture.
The tower was the home of the Chicago Tribune, Tribune Media, and Tribune Publishing. WGN Radio (720 kHz) originated broadcasts from the building until moving to 303 Wacker Drive in June, 2018. The last WGN Radio broadcast emanated from the Tribune Tower on June 18, 2018. The ground level houses the large restaurant Howells & Hood (named for the building's architects), whose patio overlooks nearby Pioneer Court and Michigan Avenue. CNN's Chicago bureau was also located in the building. It is listed as a Chicago Landmark and is a contributing property to the Michigan–Wacker Historic District. The original Tribune Tower was built in 1868, but was destroyed in the Great Chicago Fire in 1871. In early 2018, work began on converting the entire office building into condominiums, expected to be completed by 2020.
By 1922 the neo-Gothic skyscraper had become an established design tactic, with the first important so-called "American Perpendicular Style" at Cass Gilbert's Woolworth Building of 1913. This was a late example, perhaps the last important example, and criticized for its perceived historicism. Construction on the Tribune Tower was completed in 1925 and reached a height of 462 feet (141 m) above ground. The ornate buttresses surrounding the peak of the tower are especially visible when the tower is lit at night.
As was the case with most of Hood's projects, the sculptures and decorations were executed by the American artist Rene Paul Chambellan. The tower features carved images of Robin Hood (Hood) and a howling dog (Howells) near the main entrance to commemorate the architects. The top of the tower is designed after the Tour de beurre (″butter tower″) of the Rouen Cathedral in France, which is characteristic of the Late-Gothic style, that is to say, without a spire but with a crown-shaped top.
Rene Paul Chambellan contributed his sculpture talents to the buildings ornamentation, gargoyles and the famous Aesops' Screen over the main entrance doors. Rene Chambellan worked on other projects with Raymond Hood including the American Radiator Building and Rockefeller Center in New York City. Also, among the gargoyles on the Tribune Tower is one of a frog. That piece was created by Rene Chambellan to represent himself jokingly as he is of French ancestry.
