This September 11th marks 15 years since that fateful day when so many first responders who bravely served lost their lives. The Museum pay tribute with the “United We Stand, United We Signed” memorial, a temporary extension to the 9/11 and Fallen Heroes Tribute exhibit, memorializing these courageous men and women. The exhibit showcases memorial books never seen by the public from funeral homes around the nation, where people expressed their condolences following this tragedy. The Museum will also have ashes from the grounds at the Twin Towers.
