A memorial in Wappinger honors all the lives lost in the horrific attack on the United States on September 11, 2001, and calls for that day never to be forgotten. Its four flag poles symbolize the four airplanes that were sacrificed, each one taller than the last and rising upward. Two white columns represent the Twin Towers struck by the first two planes, while the Pentagon represents the third plane's target, and the plantings recall the field in Pennsylvania where the fourth plane crashed. A circle on top of the Pentagon symbolizes the unity that followed the tragedy, as Americans came together to comfort grieving hearts and restore normalcy. A steel I-beam from the Twin Towers stands for endurance and strength, and its angle of 9 degrees south by 11 degrees east represents 9/11 while also recalling how what was once true and straight was taken away. Empty boots, a coat, and a helmet recall the first responders who went to help but will never return. All of these elements are enclosed in a circle of paving stone, representing something without beginning or end that connects everything together so those who remain can never forget.
