The World Trade Center site is the 16-acre real estate on which the World Trade Center complex stood in New York until the September 11, 2001 attacks. The site is located in lower Manhattan Island and most of the site (where its buildings except 7WTC were located) is bounded to the north by Vesey Street, to the west by the West Side Highway, to the south by Liberty Street and to the east by Church Street. In the northern portion of the site across Vesey Street, the former location of 7WTC is bounded to the west by Washington Street, to the north by Barclay Street, and to the east by West Broadway. The lease for the site and its rebuilding was purchased in July 2001 by Silverstein Properties Inc. owner Larry Silverstein from the Port Authority of New York and New Jersey for $3.2 billion. A memorial named "Reflecting Absence" is being built on the site. The memorial designed by Michael Arad was the winning design of the World Trade Center Site Memorial Competition.
