The Singer Building or Singer Tower, at Liberty Street and Broadway in Lower Manhattan's Financial District, in the U.S. state of New York, was a 47-story office building completed in 1908 as the headquarters of the Singer Manufacturing Company.  It was the tallest building in the world from 1908 to 1909.  It was torn down in 1968, together with the adjacent City Investing Building, and is now the site of One Liberty Plaza.  When it was razed, it became the tallest building ever to be demolished, and is still the third-tallest building ever to be destroyed (after the World Trade Center towers) and the tallest to be purposely demolished by its owner. One Liberty Plaza, formerly the U.S. Steel Building, is a skyscraper in Lower Manhattan, in New York City, at the location of the former Singer Building (tallest structure ever dismantled) and the former City Investing Building.  One Liberty Plaza is currently owned and operated by Brookfield Office Properties.  The building is 743 ft tall and has 54 floors.  It was completed in 1973.

The park was created in 1968 by Pittsburgh-based United States Steel, after the property owners negotiated its creation with city officials.  It was named Liberty Plaza Park because it was situated beside One Liberty Plaza, which was located between Broadway, Trinity Place, Liberty Street, and Cedar Street.  The park's northwest corner is across the street from Four World Trade Center.  It has been popular with local tourists and financial workers.

Skidmore, Owings & Merrill was the designer for the office complex, and the residential complex was designed by Frank Williams.  The complex, whose component skyscrapers are among the list of tallest buildings in New York City, occupies an entire city block, bounded by Eighth Avenue, Ninth Avenue, 49th Street, and 50th Street.

Prior to the construction of Liberty Place, there was a "gentlemen's agreement" not to build any structure in Center City higher than the statue of William Penn on top of Philadelphia City Hall.  The tradition lasted until 1984 when developer Willard G. Rouse III of Rouse & Associates announced plans to build an office building complex that included two towers taller than City Hall.  There was a great amount of opposition to the construction of the towers with critics believing breaking the height limit would lead to construction of many more tall skyscrapers, ruining the livability and charm of Center City.  Despite the opposition, construction of One Liberty Place was approved and the first phase of the project began in 1985 and was completed in 1987.  When One Liberty Place was completed, it was the tallest skyscraper in Philadelphia. The Barclay Tower is a skyscraper located in the Tribeca neighborhood of Lower Manhattan, New York City.
