On September 11, 2001, terrorists attacked the United States by crashing planes into the Pentagon, a field in Pennsylvania, and the World Trade Center. Four pieces of steel from the remains of the World Trade Center are arranged to represent how they might have fallen. Twenty-two residents of the greater Prince William area were killed in the attacks that day, and their names are inscribed on the west wall of the 9/11 Liberty Memorial Reflecting Pool in Freedom Park. All who lost their lives that day are remembered and honored.
