For three decades this sculpture stood in the plaza of the World Trade Center. "The Sphere" was conceived by artist Fritz Koenig as a symbol of world peace. It was damaged by the tragic events of September 11, 2001. The Sphere was placed in Battery Park on March 11, 2002. The external flame was ignited on September 11, 2002 in honor of all those who were lost. Their spirit and sacrifice will never be forgotten.
