Chicago’s stunning cityscape has been shaped by some of the biggest names in architecture — Louis Sullivan, Frank Lloyd Wright, Mies van der Rohe, Jeanne Gang, Daniel Burnham, and beyond. No matter where you look, the city is full of architectural wonders, from soaring skyscrapers in the heart of downtown to historic landmarks in our vibrant neighborhoods.

If you’re looking to dive into Chicago architecture, explore our must-see sites and packed list of architecture events, tours, and cruises where you can learn the fascinating stories behind the buildings.

Chicago architecture styles

Art Deco: Maybe one of the most famous styles of architecture, Art Deco shines in Chicago’s downtown. Created in the exuberant optimism of the Roaring Twenties, Art Deco has come to represent opulence and glamour. One striking example is Chicago’s Carbide and Carbon Building, designed to look like a Champagne bottle and finished with real gold.

Notable examples: Carbide and Carbon Building, The Merchandise Mart, Chicago Board of Trade Building 

Chicago School: After the Great Chicago Fire, the city began to rebuild at an extraordinary pace, leveraging the latest techniques and technology to take the city’s architecture to new heights that were previously unimaginable. Legendary architects like Burnham and Root, William Le Baron Jenney, and Louis Sullivan finished these structures with decorative elements and delicate details, making Chicago School instantly recognizable. 

Notable examples: Reliance Building, Monadnock Building, Sullivan Center

International Style: The International Style is a type of modern architecture born after World War II, known for its steel-and-glass exteriors, minimal (if any) ornamentation, and open interiors. Perhaps no one did it better than Mies van der Rohe, who crafted many important Chicago buildings (the city has more of his designs than any other).

Notable examples: One Illinois Center, 330 N. Wabash

Mid-Century Modernism: This distinctive style comprises many of the Chicago skyline’s most instantly recognizable buildings. Mid-Century Modern takes the technical precision of the International Style and experiments with new materials like concrete and more sculptural, organic forms (like the iconic Marina City corn cobs).

Notable examples: 875 N. Michigan Ave., Willis Tower, Marina City

Postmodernism: Some of the city’s most eye-catching buildings are those that follow the Postmodern style. While the International style adheres to clean lines and minimal decoration, Postmodernism is all about being creative, eclectic, and sometimes a little quirky. Think curved forms, asymmetry, bright colors, and generally breaking with tradition. 

Notable examples: James R. Thompson Center, Harold Washington Library, 333 West Wacker Drive

Other architectural styles represented in Chicago include Deconstructivism (Pritzker Pavilion), Gothic Revival (Tribune Tower, Chicago Water Tower), Spanish Colonial Revival (Wrigley Building), and more.

The city’s neighborhoods are also filled with the city’s distinctive styles of residential architecture: bungalows, worker’s cottages, greystones, and more. See for yourself in our neighborhood historic districts. You’ll also find plenty of examples of Frank Lloyd Wright‘s Prairie style throughout Chicago and the surrounding suburbs.
