The Loop, one of Chicago's 77 designated community areas, is the central business district of the city and is the main section of Downtown Chicago. Home to Chicago's commercial core, it is the second largest commercial business district in North America and contains the headquarters and regional offices of several global and national businesses, retail establishments, restaurants, hotels, and theaters, as well as many of Chicago's most famous attractions. It is home to Chicago's City Hall, the seat of Cook County, and numerous offices of other levels of government and consulates of foreign nations. In it, at the intersection of State Street and Madison Street, is the origin of Chicago's street grid addresses, established in 1909. Most of Grant Park's 319 acres (1.29 km2) are in the eastern section of the community area. The Loop community area is bounded on the north and west by the Chicago River, on the east by Lake Michigan, and on the south by Roosevelt Road, although the commercial core has greatly expanded into adjacent community areas. The United States Army erected Fort Dearborn in 1803 in what is now the Loop, the first settlement in the area sponsored by the United States' federal government. When Chicago and Cook County were incorporated in the 1830s the area was selected as the site of their respective seats. Originally mixed use, the character of the area became commercial starting in the 1870s, especially after it was mostly destroyed in the Great Chicago Fire of 1871. At that time some of the world's earliest skyscrapers were constructed in the area, starting a legacy of architecture that continues to this day. In the late 19th century cable car turnarounds and a prominent elevated railway loop encircled the area, giving the Loop its name. Starting in the 1920s many highways were constructed in the Loop, most prominently U.S. Route 66, which opened in 1926 with its eastern terminus in the area. While dominated by offices and public buildings, its residential population boomed during the latter 20th century and first decades of the 21st; its population has increased the most of Chicago's community areas since 1950.

The Morrison Hotel was a high rise hotel at the corner of Madison and Clark Streets in the downtown Loop community area of Chicago, Illinois. It was designed by the architectural firm of Holabird & Roche and completed in 1925. The hotel was demolished in 1965 to make room for the First National Bank Building (now Chase Tower). The hotel was named for Orsemus Morrison, the first coroner in Chicago, who bought the site in 1838 and in 1860 built a three-story hotel with 21 rooms. Destroyed in the Great Chicago Fire of 1871, this was replaced by an eight-story building. In 1915 Harry C. Moir, who had bought the property from Morrison's nephew, built a 21-floor, 500-room hotel designed by Marshall and Fox. The hotel was expanded by 650 rooms in 1918. In 1925 the firm Holabird & Roche further expanded it, adding a 46-story tower. The hotel had 1,800 rooms in 1931. A fourth, 21-story section was then added, bringing the number of rooms to 2,210, but was sold in 1937, becoming the Hotel Chicagoan; in the 1950s this was operated under lease by the Morrison. In 1952 a syndicate bought the Morrison and renovated it.The 1873 Morrison Hotel housed the Boston Oyster House in its basement. In the skyscraper hotel, the Terrace Casino opened in 1936 with a performance by Sophie Tucker and was an important Big Band venue; the Carousel in the Sky was the world's highest nightclub; the Jockey Club on the first floor was the site of protests by the National Association for the Advancement of Colored People that forced removal of its black jockey statues. Presidents Truman, Eisenhower, and Kennedy and Vice-Presidents Barkley and Nixon stayed at the hotel; boxer Jack Dempsey was also a frequent guest. Gorgeous George was a daily client of the beauty parlor. From 1932 on, the headquarters of the Cook County Democratic machine was on the third floor of the Morrison. Joe "Hold 'Em" Powers spent a world record 16 days on the hotel flagpole in 1927, despite losing six teeth when wind blew him into cables.In 1931, the Air Line Pilots Association was founded in the hotel's ballroom.In June of 1937, the hotel served as the location in which the Chicago Herald-Examiner kept the notorious murderer Robert Irwin sequestered while negotiating terms of his surrender to authorities in Manhattan.Standing 526 feet (160 m) high, the Morrison Hotel was the first building outside of New York City to have more than 40 floors, and for thirty years was the world's tallest hotel. At the time of its razing in 1965, it was the tallest building to have ever been demolished anywhere in the world. At the time it was demolished, it was still the tallest hotel in Chicago.

McVicker's Theater (1857–1984) was a playhouse in Chicago, Illinois, United States. Built for actor James Hubert McVicker, the theater was the leading stage for comedic plays in Chicago's early years. It often hosted performances by Edwin Booth, who married McVicker's daughter and was once targeted there in an attempted murder. Adler & Sullivan designed a remodel in 1883. Although destroyed in two fires, including the Great Chicago Fire, McVicker's remained an operating theater until 1984. It was demolished the next year.

The Chicago flood occurred on April 13, 1992, when repair work on a bridge spanning the Chicago River damaged the wall of an abandoned and disused utility tunnel beneath the river. The resulting breach flooded basements, facilities and the underground Chicago Pedway throughout the Chicago Loop with an estimated 250 million US gallons (1,000,000 m3) of water. The remediation lasted for weeks, and cost about $2 billion in 1992 dollars, equivalent to $3.86 billion in 2021. The legal battles lasted for several years, and disagreement over who was at fault persists to this day.
