140 Broadway (formerly known as the Marine Midland Building or the HSBC Bank Building) is a 51-story International Style office building on the east side of Broadway between Cedar and Liberty streets in the Financial District of Manhattan in New York City. The building was designed by Gordon Bunshaft, of the firm Skidmore, Owings & Merrill, and consists of a mostly smooth black facade on a trapezoidal plot. It is approximately 688 ft tall, with approximately 1.17 e6sqft. It is known for the distinctive sculpture at its entrance, Isamu Noguchi's Cube.
The developer Erwin S. Wolfson acquired the site in several stages between 1952 and 1961. Initial plans called for a 36-story monolith, but when Wolfson died, the architects modified their plans to a 51-story tower, which occupied only two-fifths of the block and conformed to the 1961 Zoning Resolution. The building was erected between late 1964 and 1967 and was originally known for its main tenant, the Marine Midland Corporation (later part of HSBC). Several early tenants were affiliated with the financial industry, including banking and accounting firms. In 1998, the building was sold to Silverstein Properties, which undertook a major renovation.
The primary tenant of the building since 2002 is Brown Brothers Harriman, filling a vacancy left after HSBC relocated in 2001. The building has been owned by Union Investment since 2004, and the New York City Landmarks Preservation Commission designated the building as a city landmark in 2013.
