200 Liberty Street, formerly known as One World Financial Center, is one of four towers that comprise the Brookfield Place complex in the Financial District of Lower Manhattan in New York City. Rising 40 floors and 577 ft, it is situated between the Hudson River and the World Trade Center. The building is on Liberty Street between South End Avenue and West Street. The building opened in 1986 as part of the World Financial Center and was designed by Cesar Pelli & Associates. It has a leasable area of 1628000 sqft. Similarly to other WFC buildings it has a unique roof which is designed to resemble a Mastaba, which is a truncated square pyramid, and follows the theme of using ancient structures as the roofs for the rest of the WFC (the other tops are a dome, a pyramid and a stepped pyramid). It is connected to the rest of the complex by a skybridge over Liberty Street. The building is located across the street from the World Trade Center site and was significantly damaged in the September 11 attacks. The initial dust cloud and other explosions shattered many windows, heavily damaging nearby Winter Garden Atrium and other buildings of the World Financial Center complex. It was closed for several months and reopened in 2002 after extensive restoration. It was renamed 200 Liberty Street when the rest of the complex became Brookfield Place in 2014.
