Chicago’s skyline has not always been filled with gleaming skyscrapers. The Great Chicago Fire in 1873 wiped out most of the city, displacing one-third of its residents. Though a tragedy, the fire led to improved building materials and fire codes, which paved the way for the age of the skyscraper.
The skyline you see today is an amalgamation of more than a century of various architectural styles, building materials, attainable heights, and sustainability efforts.
