The World Trade center Sphere

The Sphere is a large metallic sculpture by German sculptor Fritz Koenig, currently displayed in Battery Park, that once stood in the middle of Austin Tobin Plaza, the area between the World Trade Center towers in Manhattan. After being recovered from the rubble of the Twin Towers after the September 11, 2001 attacks, its fate was initially uncertain and it was dismantled into its components. Although it remained structurally intact, it had been visibly damaged by debris from the airliners that were crashed into the buildings and the collapsing skyscrapers themselves.
