Flamingo (sculpture)

The United States Custom House, Court House, and Post Office was a federal government building from the 1870s to 1896 in the block bounded by Adams Street, Jackson Boulevard, Dearborn Street, and Clark Street in the Chicago Loop

The Kluczynski Federal Building is a skyscraper in the downtown Chicago Loop located at 230 South Dearborn Street. The 45-story structure was designed by Ludwig Mies van der Rohe and completed in 1974 as the last portion of the new Federal Center. It is 562 feet (171 m) tall and with the Mies designed post office and plaza stands on the site previously occupied by the Chicago Federal Building by the architect Henry Ives Cobb. It was named in honor of U.S. Congressman John C. Kluczynski, who represented Illinois's 5th congressional district from 1951 to 1975 after his death that year. This is one of three buildings by van der Rohe in the Federal Center Plaza complex: the others are the Loop Station Post Office and the Everett McKinley Dirksen United States Courthouse. The Kluczynski Building is constructed of a steel frame and contains 1,200,000 sq ft (110,000 m2) of space. The exterior is sheathed in bronze-tinted glass set into bright aluminum frames. Beneath the windows are steel spandrel panels painted flat black and windows are separated horizontally by steel mullions of projecting steel I-beams also painted black. The two-story lobby is recessed allowing for a colonnade or pilotis to encircle the building at street level. The interior walls and floors of the lobby are covered in granite which extends to the plaza. The lobby contains several commemorative tablets which were removed from the previous building. The entire complex is based on a 28 ft (8.5 m) grid pattern so that seams of the granite pavers in the plaza extend into the building lobbies and up the sides to create unity among the three structures. The Center is similar to Mies' earlier Toronto-Dominion Centre and was expanded in 1991 with the addition of the 28-story Metcalfe Federal Building to the south across Jackson Boulevard.In 2009, GSA undertook a major project to improve energy efficiency which included solar film on windows, LED lighting upgraded HVAC and other mechanical systems. After the work, the building received a LEED Silver certification.Alexander Calder's sculpture Flamingo, a 53-foot (16 m) red steel sculpture, was unveiled on the plaza October 24, 1974. The sculpture was conserved and restored in 1998. The plaza is also the site of a weekly farmers' market during the spring and summer seasons, open to the community. Federal agencies in the building include the Air Force Recruiting Service, the Department of State Passport Agency, Department of Labor, Internal Revenue Service, Office of Personnel Management, Consumer Product Safety Commission, General Services Administration and offices for both the U.S. senators from Illinois, Richard "Dick" Durbin and Tammy Duckworth.Following his election as president on November 4, 2008, Barack Obama established his administration's transitional offices in the federal building, prompting heightened security measures in the surrounding area.

The Chicago Tunnel Company was the builder and operator of a 2 ft (610 mm) narrow-gauge railway freight tunnel network under downtown Chicago, Illinois. This was regulated by the Interstate Commerce Commission as an interurban even though it operated entirely under central Chicago, did not carry passengers, and was entirely underground. It inspired the construction of the London Post Office Railway.

The Everett McKinley Dirksen United States Courthouse, commonly referred to as the Dirksen Federal Building, is a skyscraper in the Chicago Loop at 219 South Dearborn Street. It was designed by Ludwig Mies van der Rohe and completed in 1964. The building is 384 feet (117 m) tall with 30 floors; it was named for U.S. Congressman Everett Dirksen. The building houses the United States Court of Appeals for the Seventh Circuit, the United States District Court for the Northern District of Illinois, the United States Bankruptcy Court, the United States Marshal for the Northern District of Illinois, United States Attorney for the Northern District of Illinois, and local offices for various court-related federal agencies, such as the Federal Public Defender, United States Probation Service, United States Trustee, and National Labor Relations Board. It is one of three buildings making up the modernist Chicago Federal Center complex designed by van der Rohe, along with Federal Plaza, the U.S. Post Office (Loop Station) and the Kluczynski Federal Building. Separate from the Federal Plaza, but opposite the Kluczynski Building across Jackson Boulevard, is the Metcalfe Federal Building.

Great Northern Hotel was a historic hotel in Chicago's Loop area. It was located at the northeast corner of Jackson Boulevard and Dearborn Street in Chicago, Illinois. The building was designed by Burnham and Root. They created a new design, with an urban office block floor plan that was free of historical or European influences. The site is now occupied by the Dirksen Federal Building.

The Chicago Federal Building in Chicago, Illinois was constructed between 1898 and 1905 for the purpose of housing the Midwest's federal courts, main post office, and other government bureaus. It stood in The Loop neighborhood on a block bounded by Dearborn, Adams and Clark Streets and Jackson Boulevard. The site held an 1880 post office, courthouse and customhouse which was cleared to make way for the new building. The 1905 building was itself demolished in 1965 and replaced with the Kluczynski Federal Building. The push for a new building was spearheaded by postmaster Washington Hesing with backing by civic leaders and Illinois's members of Congress. The explosion of Chicago's population, especially after the World's Columbian Exposition of 1893, strained the earlier facility beyond capacity. When the Exposition began, the Post Office Department in Chicago employed 998 clerks and 935 carriers. By the time Congress approved funding for a new building, the post office had expanded to 1,319 clerks and 1,096 carriers. Other agencies housed in the building complained of poor planning and shoddy construction which resulted in crumbling plaster, broken plumbing and flooding.The new building was designed in the Beaux-Arts style by architect Henry Ives Cobb. The floorplan was a six-story Greek cross atop a two-story base with a raised basement. The building was capped by a dome at the crossing that held an additional eight floors of office space in its drum for a total of 16 floors. The gilt dome extended 100 ft (30 m) above the drum.

Jackson (also Jackson/Dearborn) is an 'L' station on the CTA's Blue Line, located in the Loop. This station was recently renovated to resemble the Jackson/State station; a pedestrian tunnel connects these two stations, allowing for a free transfer to the Red Line. Farecard transfers to the Harold Washington Library – State/Van Buren station are also available at this station for the Brown, Orange, Pink, and Purple Lines. This is the southernmost of the three stations on one long continuous platform underneath Dearborn Street, with the stops at Monroe and Washington being the other two.

The Marquette Building, completed in 1895, is a Chicago landmark that was built by the George A. Fuller Company and designed by architects Holabird & Roche. The building is currently owned by the John D. and Catherine T. MacArthur Foundation. It is located in the community area known as the "Loop" in Cook County, Illinois, United States. The building was one of the early steel frame skyscrapers of its day, and is considered one of the best examples of the Chicago School of architecture. The building originally had a reddish, terra cotta exterior that, prior to restoration, was somewhat blackened due to decades of Loop soot. It is noted both for its then cutting edge frame and its ornate interior. Since construction, the building has received numerous awards and honors. It was designated a Chicago Landmark on June 9, 1975, and is considered an architectural masterpiece. It was added to the National Register of Historic Places on August 17, 1973 and named a National Historic Landmark on January 7, 1976. The building's preservation has been a major focus of the Landmarks Preservation Council of Illinois. The John D. and Catherine T. MacArthur Foundation completed an extensive four-year restoration in 2006.

The Union League Club of Chicago is a prominent civic and social club in Chicago that was founded in 1879. Its second and current clubhouse is located at 65 W Jackson Boulevard on the corner of Federal Street, in the Loop neighborhood of Chicago. The club is considered one of the most prestigious in Chicago, ranking fifth in the United States and second in Chicago on the Five Star Platinum Club list. Union League clubs, which are legally separate but share similar histories and maintain reciprocal links with one another, are also located in New York City and Philadelphia. Additional Union League clubs were formerly located in Brooklyn, New York and New Haven.

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.

The Monadnock Building (historically the Monadnock Block; pronounced mə-NAD-nok) is a 16-story skyscraper located at 53 West Jackson Boulevard in the south Loop area of Chicago. The north half of the building was designed by the firm of Burnham & Root and built starting in 1891. The tallest load-bearing brick building ever constructed, it employed the first portal system of wind bracing in America. Its decorative staircases represent the first structural use of aluminum in building construction. The later south half, constructed in 1893, was designed by Holabird & Roche and is similar in color and profile to the original, but the design is more traditionally ornate. When completed, it was the largest office building in the world. The success of the building was the catalyst for an important new business center at the southern end of the Loop. The building was remodeled in 1938 in one of the first major skyscraper renovations ever undertaken—a bid, in part, to revolutionize how building maintenance was done and halt the demolition of Chicago's aging skyscrapers. It was sold in 1979 to owners who restored the building to its original condition, in one of the most comprehensive skyscraper restorations attempted as of 1992. The project was recognized as one of the top restoration projects in the US by the National Trust for Historic Preservation in 1987. The building is divided into offices from 250 square feet (23 m2) to 6,000 square feet (560 m2) in size, and primarily serves independent professional firms. It was listed for sale in 2007. The north half is an unornamented vertical mass of purple-brown brick, flaring gently out at the base and top, with vertically continuous bay windows projecting out. The south half is vertically divided by brickwork at the base and rises to a large copper cornice at the roof. Projecting window bays in both halves allow large exposures of glass, giving the building an open appearance despite its mass. The Monadnock is part of the Printing House Row District, which also includes the Fisher Building, the Manhattan Building, and the Old Colony Building. When it was built, many critics called the building too extreme, and lacking in style. Others found in its lack of ornamentation the natural extension of its commercial purpose and an expression of modern business life. Early 20th-century European architects found inspiration in its attention to purpose and functional expression. It was one of the first buildings named a Chicago Architectural Landmark in 1958. It was added to the National Register of Historic Places in 1970, and named as part of the National Historic Landmark South Dearborn Street – Printing House Row North Historic District in 1976. Modern critics have called it a "classic", a "triumph of unified design", and "one of the most exciting aesthetic experiences America's commercial architecture produced".

The Berghoff restaurant, at 17 West Adams Street, near the center of the Chicago Loop, was opened in 1898 by Herman Joseph Berghoff and has become a Chicago landmark.
