Girders in the shape of a cross, preserved from the wreckage of the World Trade Center (WTC), stand over the WTC site in New York September 10, 2004. New York City plans to mark the third anniversary of the attacks on the trade center with an observance at the site on September 11 with parents and grandparents of victims reading their names. The American flag is reflected on the surface of the new 7 World Trade Center Building, under construction, at rear. The original 7 World Trade Center, which stood at the same location, burned and collapsed in the attack three years ago.
