Chicago ( (listen) shih-KAH-goh, locally also shih-KAW-goh), officially the City of Chicago, is the most populous city in the U.S. state of Illinois, and the third-most populous city in the United States, following New York City and Los Angeles. With a population of 2,746,388 in the 2020 census, it is also the most populous city in the Midwestern United States and the fifth most populous city in North America. Chicago is the county seat of Cook County, the second most populous county in the U.S., while a small portion of the city's O'Hare International Airport also extends into DuPage County. Chicago is the principal city of the Chicago metropolitan area, defined as either the U.S. Census Bureau's metropolitan statistical area (9.6 million people) or the combined statistical area (almost 10 million residents), often called Chicagoland. It is one of the 40 largest urban areas in the world. Located on the shores of freshwater Lake Michigan, Chicago was incorporated as a city in 1837 near a portage between the Great Lakes and the Mississippi River watershed. It grew rapidly in the mid-19th century; by 1860, Chicago was the youngest U.S. city to exceed a population of 100,000. Even after the Great Chicago Fire of 1871 destroyed several square miles and left more than 100,000 homeless, Chicago's population grew to 503,000 by 1880 — and then doubled to more than a million within the decade. The construction boom accelerated population growth throughout the following decades, and by 1900, less than 30 years after the great fire, Chicago was the fifth-largest city in the world. Chicago made noted contributions to urban planning and zoning standards, including new construction styles (including the Chicago School of architecture), the development of the City Beautiful Movement, and the steel-framed skyscraper.Chicago is an international hub for finance, culture, commerce, industry, education, technology, telecommunications, and transportation. It is the site of the creation of the first standardized futures contracts, issued by the Chicago Board of Trade, which today is part of the largest and most diverse derivatives market in the world, generating 20% of all volume in commodities and financial futures alone. O'Hare International Airport is routinely ranked among the world's top six busiest airports according to tracked data by the Airports Council International. The region also has the largest number of federal highways and is the nation's railroad hub. The Chicago area has one of the highest gross domestic products (GDP) in the world, generating $689 billion in 2018. The economy of Chicago is diverse, with no single industry employing more than 14% of the workforce. It is home to several Fortune 500 companies, including Abbott Laboratories, AbbVie, Allstate, Archer Daniels Midland, Boeing, Caterpillar, Conagra Brands, Exelon, JLL, Kraft Heinz, McDonald's, Mondelez International, Motorola Solutions, Sears, United Airlines Holdings, US Foods, and Walgreens.Chicago's 58 million tourist visitors in 2018 set a new record.

Madison Street is a major east–west street in Chicago, Illinois. Prior to human intervention, the Chicago River emptied into Lake Michigan at the present day intersection of Madison Street and Michigan Avenue. Per a 1908 decision by Chicago's city council, Madison serves as the north–south dividing line for Chicago's street numbering system, while State Street serves as the east–west line. At one point, the intersection between the two streets was considered the "world's busiest corner." Notable buildings located along Madison Street include the Carson, Pirie, Scott and Company Building, Chase Tower, Three First National Plaza, the Chicago Civic Opera House, Citigroup Center and the United Center. The Chicago Stadium was situated across the street from the United Center until it was demolished in 1995.

The Chicago Building or Chicago Savings Bank Building is an early skyscraper, built in 1904–1905. It is located at 7 W. Madison Street in Chicago. Designed by the architecture firm Holabird & Roche, it is an early and highly visible example of the Chicago school of architecture. The building's features characterize this style through the use of large "Chicago windows", metal frame construction, distinctive bays, and terra cotta cladding. The combination of the north side projecting bay windows, and the east side rectangular "Chicago windows" with movable sashes is representative of the two typical Chicago school window types. The building is prominently located on the southwest corner of State Street and Madison Street, with visibility increased by an offset in the alignment of State Street. The building is a critical component of a grouping of significant structures, including Carson Pirie Scott and the former Mandel Brothers Store, at what was once labeled the "World's Busiest Corner". The building was designated a Chicago landmark on March 26, 1996. In 1997, it was converted to a dormitory for the School of the Art Institute of Chicago. The corner of the 3rd floor of the Chicago Building contains the cornerstone of Chicago. It is the 0-0 degree point of the city, and is the location from which all addresses in Chicago begin.

The Heyworth Building is a Chicago Landmark located at 29 East Madison Street, on the southwest corner of Madison Street and Wabash Avenue in Chicago, Illinois. The building was constructed in 1904 by the architectural firm of D. H. Burnham & Company under the commission of Otto Young, a real estate investor and wholesale jeweler. It received its name from the son in law of Otto Young, Lawrence Heyworth, who also supervised construction of the building. Like many other buildings along Wabash Avenue, the Heyworth historically housed watchmakers, jewelers, and associated businesses. This structure was one of the final buildings designed by Frederick P. Dinkelberg at the firm before administration was turned over to Ernest Robert Graham.The Heyworth stands 19 stories tall with a gross square footage of 256,000 square feet (23,800 m2). Its style strays from the typical designs of Burnham and Root, appearing more rigid and geometrical than their other works done in a classical style. It combined the Chicago School's structurally expressive character with decorative appearance common in traditional masonry architecture. The tapestry-like ornament of the building pairs well with the ornamentation designed by Louis Sullivan on the adjacent Sullivan Center building. The Heyworth is also noted for its intact finely crafted decorative cornice, which is an uncommon feature among the other commercial buildings of Chicago. The building was designated a Chicago Landmark on August 30, 2000. According to a real estate firm that manages the property, the height of the building is listed in various documents as 260, 273, and 282 feet (86 m). The building was provided an $11 million renovation in 2001. As part of the renovation, the facade was cleaned and the famous cornice was rebuilt after having undergone a stripping in years past. It is currently the home of Computer Systems Institute, the ESL Academy's Chicago campus, MacCormac College in Chicago and to the Center for Economic Progress.

The Reliance Building was listed on the National Register of Historic Places in 1970; and on January 7, 1976, it was designated a National Historic Landmark.The Reliance Building is also part of the Loop Retail Historic District, a collection of over one hundred buildings that reflects the growth of State and Wabash Streets as the central retail district of Chicago.
