875 North Michigan Avenue, long known as the John Hancock Center, is a 100-story mixed-use skyscraper on Chicago’s Magnificent Mile and one of the city’s defining landmarks. Designed by Bruce Graham and Fazlur Rahman Khan at Skidmore, Owings and Merrill, it is distinguished by its X-braced exterior and tubular structural system, which helped it reach 1,128 feet while allowing open interior space. When it topped out in 1968, it was the tallest building in Chicago and second-tallest in the world. Despite construction setbacks and later ownership changes, it has remained a major residential, office, observation, and broadcasting tower with a lasting place in Chicago’s skyline and identity.
