Daniel Burnham in the context of "Flatiron Building"

The World's Columbian Exposition, also known as the Chicago World's Fair, was a world's fair held in Chicago from May 1 to October 31, 1893, to celebrate the 400th anniversary of Christopher Columbus's arrival in the New World in 1492. The centerpiece of the Fair, held in Jackson Park, was a large water pool representing the voyage that Columbus took to the New World. Chicago won the right to host the fair over several competing cities, including New York City, Washington, D.C., and St. Louis. The exposition was an influential social and cultural event and had a profound effect on American architecture, the arts, American industrial optimism, and Chicago's image.

The layout of the Chicago Columbian Exposition was predominantly designed by John Wellborn Root, Daniel Burnham, Frederick Law Olmsted, and Charles B. Atwood. It was the prototype of what Burnham and his colleagues thought a city should be. It was designed to follow Beaux-Arts principles of design, namely neoclassical architecture principles based on symmetry, balance, and splendor. The color of the material generally used to cover the buildings' façades, white staff, gave the fairgrounds its nickname, the White City. Many prominent architects designed its 14 "great buildings". Artists and musicians were featured in exhibits and many also made depictions and works of art inspired by the exposition. One particularly notable attraction was the world's first ferris wheel, standing at a height of 264 feet, which was designed to rival the Eiffel Tower built for the 1889 World's Fair four years earlier.

Washington Union Station, known locally as Union Station, is a major train station, transportation hub, and leisure destination in Washington, D.C. Designed by Daniel Burnham and opened in 1907, it is Amtrak's second-busiest station and North America's 13th-busiest railroad station. The station is the southern terminus of the Northeast Corridor, an electrified rail line extending north through major cities including Baltimore, Philadelphia, New York City, and Boston, and the busiest passenger rail line in the nation. In 2015, it served just under five million passengers.

An intermodal facility, Union Station also serves MARC and VRE commuter rail services, the Washington Metro, the DC Streetcar, intercity bus lines, and local Metrobus buses. It carries the IATA airport code of ZWU.

The Sullivan Center, formerly known as the Carson, Pirie, Scott and Company Building or Carson, Pirie, Scott and Company Store, is a commercial building at 1 South State Street at the corner of East Madison Street in Chicago, Illinois. Louis Sullivan designed it for the retail firm Schlesinger & Mayer in 1899 and later expanded it before H.G. Selfridge & Co. purchased the structure in 1904. That firm occupied the structure for only a matter of weeks before it sold the building (the land under it was owned at the time by Marshall Field) to Otto Young, who then leased it to Carson Pirie Scott for $7,000 per month, which occupied the building for more than a century until 2006. Subsequent additions were completed by Daniel Burnham in 1906 and Holabird & Root in 1961.

The building has been used for retail purposes since 1899, and has been a Chicago Landmark since 1975. It is part of the Loop Retail Historic District.

Selfridges Retail Limited (doing business as Selfridges and occasionally Selfridges & Co.) is a British department store chain. It was founded by Harry Gordon Selfridge in 1909. The historic Daniel Burnham-designed Selfridges flagship store at 400 Oxford Street in London opened on 15 March 1909 and is the second-largest shop in the UK (after Harrods). Other Selfridges stores opened in the Manchester area at the Trafford Centre (1998) and at Exchange Square (2002), and in Birmingham at the Bullring (2003).

During the 1940s, smaller provincial Selfridges stores were sold to the John Lewis Partnership, and in 1951, the original Oxford Street store was acquired by the Liverpool-based Lewis's chain of department stores. Lewis's and Selfridges were then taken over in 1965 by the Sears Group, owned by Charles Clore. Expanded under the Sears Group to include branches in Manchester and Birmingham, the chain was acquired in 2003 by Canada's Galen Weston for £598 million. In December 2021, the Weston family agreed to sell the majority of Selfridges Group for around £4 billion to a joint venture between Thai conglomerate Central Group and Austria's Signa Holding. The acquisition was completed on 23 August 2022. However, after Signa faced financial difficulties and declared bankruptcy, Saudi Arabia's Public Investment Fund (PIF) acquired Signa's shares in Selfridges, becoming a co-owner alongside the Central Group.

John Wellborn Root (January 10, 1850 – January 15, 1891) was an American architect who was based in Chicago with Daniel Burnham. He was one of the founders of the Chicago School style. Two of his buildings have been designated National Historic Landmarks (the Rookery, and the Reliance); others have been designated Chicago landmarks and listed on the National Register of Historic Places. In 1958, he was posthumously awarded the AIA Gold Medal.
