Rebuilding ground zero the world trade center site

                      The World Trade Center site, also known as "Ground Zero" after the September 11 attacks, sits on 16 acres in Lower Manhattan in New York City. The World Trade Center complex stood on the site until it was destroyed in the 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. Developer Larry Silverstein holds the lease to retail and office space in four of the site's buildings.
