The World Trade Center site was publicly owned but privately leased shortly before 9/11.

Who “owned” the World Trade Center?

  • The legal owner of the original World Trade Center complex (including the Twin Towers) was the Port Authority of New York and New Jersey, a bi‑state public agency.
  • In 2001, the Port Authority decided to privatize operations by granting a long‑term lease to a private developer rather than selling the land outright.
  • In July 2001, a consortium led by Larry Silverstein’s company, Silverstein Properties, signed a 99‑year lease for most of the complex, in a deal worth about 3.2 billion dollars.
  • That lease made Silverstein Properties the private leaseholder and day‑to‑day controller of the Twin Towers and several surrounding buildings, while the Port Authority still owned the land and underlying public interest.

So, in everyday terms, people often say “Larry Silverstein owned the World Trade Center,” but technically he leased it; the Port Authority remained the ultimate public owner of the site.

Before and after 9/11 (quick timeline)

  1. 1973–1990s: Original era
    • Complex developed and owned by the Port Authority from the start, functioning as a major symbol of U.S. economic power and globalization.
  1. Late 1990s–July 2001: Move to privatize
    • The Port Authority decided in 1998 to lease the complex to a private operator.
 * After bidding rounds and a failed initial deal with another firm, Silverstein Properties secured the long lease and “took the keys” on July 24, 2001.
  1. Post‑9/11: Rebuilding and rights
    • After the attacks, Silverstein Properties remained central in negotiations over insurance payouts and rebuilding rights at the site.
 * A 2006 agreement split responsibilities: the Port Authority controls One World Trade Center and some future towers, while Silverstein retains rights to develop several other office towers on the site.

Simple takeaway

  • Public owner: Port Authority of New York and New Jersey (land and overall site).
  • Private leaseholder at the time of 9/11: Larry Silverstein/Silverstein Properties under a 99‑year lease signed in July 2001.
