28 Liberty Street, formerly known as One Chase Manhattan Plaza, is a 60-story International Style skyscraper between Nassau, Liberty, William, and Pine Streets in the Financial District of Manhattan in New York City. The building, designed by Gordon Bunshaft of Skidmore, Owings & Merrill (SOM), opened in 1961. It is tall.

28 Liberty Street occupies only about 28 percent of its site. It consists of 60 above-ground stories, a ground-level concourse, and five basement levels. The tower is surrounded by a plaza that contains a sunken Japanese rock garden, designed by Isamu Noguchi, to the south. The building's design is similar to that of SOM's earlier Inland Steel Building in Chicago. It contains a stainless steel facade with black spandrels below the windows. The superstructure contains 40 steel columns, arranged around the perimeter and clustered around the core to maximize usable space. When the tower opened, it accommodated 7,500 employees but contained only 150 private offices.

David Rockefeller, then executive vice president of Chase Manhattan Bank, proposed the tower in the 1950s as a means to keep the newly merged bank (Chase National and the Manhattan Company) in Lower Manhattan while merging its 8,700 employees into one facility. Construction started in early 1957, and the building's tower opened in early 1961. One Chase Manhattan Plaza was nearly fully occupied from its opening, with numerous financial and legal tenants. The building's basements and plaza opened in 1964; during its early years, the structure faced some early challenges such as the discovery of weakened facade panels, a fire, and a bombing. The building was renovated in the early 1990s, and Chase moved its headquarters out in 1997. The New York City Landmarks Preservation Commission designated the building a landmark in 2008. Chase Manhattan's parent company, JPMorgan Chase, sold the building to Fosun International, a Chinese investment company, in 2013; the building was subsequently renamed 28 Liberty Street.

Site

28 Liberty Street is on the northern half of a city block bounded to the west by Nassau Street, to the north by Liberty Street, to the east by William Street, and to the south by Pine Street. Its plaza is on the southeastern portion of the site, while the southwestern portion is occupied by 20 Pine Street, which had been Chase Manhattan Bank's previous headquarters. The site slopes down to the north so the plaza is at the elevation of Pine Street, while Liberty Street is one story beneath the plaza; there are five basements under the plaza. There are stairs leading down the east side of the plaza to Cedar Street.

Within 28 Liberty Street's immediate surroundings are the Federal Reserve Bank of New York Building to the north; the Chamber of Commerce Building and Liberty Tower to the northwest; 140 Broadway to the west; and the Equitable Building to the southwest. The public plaza faces Federal Hall National Memorial to the southwest and 40 Wall Street to the south.

The block was formerly two smaller city blocks, separated by Cedar Street, which ran west to east. The Middle Collegiate Church was built on the northern portion of the lot in 1731. Later becoming the city's main Post Office in the mid-19th century, the church building was torn down in 1882. The building site then served as the headquarters of the Mutual Life Insurance Company of New York starting in 1884. Four of the firm's thirteen general partners were most involved with 28 Liberty Street's design, namely Gordon Bunshaft, Edward James Mathews, Nathaniel A. Owings, and J. Walter Severinghaus. Bunshaft, who was tasked with the building's general design, passed most of the planning responsibilities to Roy O. Allen and Jacques E. Guiton, since Bunshaft was also involved in several other projects at the time. Three contractors were hired to excavate the foundations, while Turner Construction was hired as the general contractor.
