The World Trade Center site (ZIP code: 10048), formerly known as "Ground Zero" after the September 11 attacks, sits on 16 acres (65,000 m²) in Lower Manhattan in New York City. The previous World Trade Center complex stood on the site until it was destroyed in the September 11 attacks; Studio Daniel Libeskind, the Port Authority of New York and New Jersey, Silverstein Properties, and the Lower Manhattan Development Corporation oversee the reconstruction of the site. The site is bounded by Vesey Street to the north, the West Side Highway to the west, Liberty Street to the south, and Church Street to the east. The Port Authority owns the site's land (except for 7 World Trade Center).
