Tribune Tower

Address: 435 N. Michigan Ave. Year Built: 1922 - 1925 Architect: Howells & Hood Date Designated a Chicago Landmark: February 1, 1989

This design was the result of an international competition for "the most beautiful office building in the world," held in 1922 by the Chicago Tribune newspaper. The various competition entries proved extremely influential for the development of skyscraper architecture in the 1920s. The winning entry, with a crowning tower with flying buttresses, is derived from the design of the French cathedral of Rouen and gives the building its striking silhouette. The base of the building is studded with over 120 stones from famed sites and structures in all 50 states and dozens of foreign countries. They range from the Parthenon (Greece) and Taj Mahal (India) to Bunker Hill (Massachusetts) and Mark Twain's "Injun Joe Cave" (Missouri).
