2. The Sphere Once Stood on the Plaza of the World Trade Center

The Sphere, standing twenty-five feet tall, was to symbolize world peace through world trade, and for three decades stood at the center of the plaza of the World Trade Center. Five months after the September 11 attacks, the sculpture was recovered from the rubble and moved to The Battery on March 11, 2002 and formally rededicated with an eternal flame on September 11, 2002, as a memorial to the victims of September 11.
