The bronze sculpture, which stood in the fountain of the World Trade Center plaza, was dedicated as a temporary memorial six months after the terrorist attacks of Sept. 11th.

New York - The sculpture The Sphere Plaza Fountain, which stood in front of New York's World Trade Center before the September 11, 2001 attacks, is set to return to the site.

Unveiled in 1971, even before the completion of the Twin Towers two years later, the 25-foot (eight-meter) centrepiece by the German artist Fritz Koenig was only partly damaged during the buildings' collapse.

Removed from the site, it was installed in several places before ending up in Battery Park at Manhattan's southern tip for the past 14 years.

The Sphere is now set to be installed in Liberty Park, a new elevated garden at the World Trade Center opened last month, the Port Authority of New York and New Jersey said in a statement .

With the sculpture's original location in the middle of what is now a newly restored street, the 23-ton bronze artwork will overlook the memorial to victims of the attack.
