Located in the Magnificent Mile district, its name was changed to 875 North Michigan Avenue in 2018. Despite this, the building is still colloquially called the John Hancock Center. The skyscraper was constructed under the supervision of Skidmore, Owings and Merrill (SOM), by SOM partners, Peruvian-US chief designer Bruce Graham and Bangladeshi-US structural engineer Fazlur Rahman Khan. When the building topped out on May 6, 1968, it was the second-tallest building in the world after the Empire State Building, and the tallest in Chicago.
