World Trade Center cross
United States
The World Trade Center cross, also known as the Ground Zero cross, is a formation of steel beams found among the debris of the World Trade Center site in Lower Manhattan, New York City, following the September 11 attacks in 2001. This set of beams is named for its resemblance to the proportions of a Christian cross. Since 2014, the beams have been part of an exhibit at the September 11 Museum.
