Which type of structure is emphasized in Chicago's architectural landscape?

In Chicago's architectural landscape, skyscrapers are emphasized due to the city's historical development and its role as a hub of innovation in architecture and engineering. The rise of the skyscraper in Chicago began in the late 19th century, particularly after the Great Chicago Fire of 1871, which led to the reconstruction of the city and facilitated experimentation with steel-frame construction. This technology allowed for the creation of taller and more complex buildings.

Throughout the 20th century, Chicago became known for its iconic skyscrapers, such as the Willis Tower (formerly Sears Tower), the John Hancock Center, and the Aon Center. These structures are not only symbols of the city but also represent significant advancements in architectural design, such as the development of curtain wall façades and innovative structural systems. Chicago's commitment to skyscraper construction reflects its identity as a major urban center and has influenced architectural practices globally.

Other building types listed, such as townhouses, single-family homes, and commercial plazas, while present in the city, do not capture the distinctive character and historical significance associated with Chicago's skyline and its pioneering role in vertical construction.
