Detail of the sculpture
|Year||1972 - 2001|
|Dimensions||7.2 m × 5.9 m × 8.7 m (23.5 ft × 19.5 ft × 28.5 ft)|
|Condition||Destroyed in September 2001 WTC Attacks|
Located between the Twin Towers, in front of the Marriott World Trade Center, the work was lost in the September 11 attacks. Though the sculpture may have survived the attacks and collapse of the buildings, its steel material was indistinguishable from the Ground Zero rubble. As a result, the sculpture was never recovered, and its remains were removed from Ground Zero along with the rest of the rubble. 
According to Saul Wenegrat, former director of the art program for the Port Authority, the sculpture may have been the most photographed piece of art in the World Trade Center Complex. It was also featured in many fashion advertisements.
