The World Trade Center site, often referred to as "Ground Zero" or "the Pile" immediately after the September 11 attacks, is a 14.6-acre (5.9 ha) area in Lower Manhattan in New York City. 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). The original World Trade Center complex stood on the site until it was destroyed in the September 11 attacks.
The Port Authority of New York and New Jersey (PANYNJ), Silverstein Properties, and the Lower Manhattan Development Corporation (LMDC) have overseen the reconstruction of the site as part of the new World Trade Center, following a master plan by Studio Daniel Libeskind. Developer Larry Silverstein holds the lease to retail and office space in four of the site's buildings.
