Temple University marks the 25th anniversary of the September 11 attacks with a solemn remembrance ceremony at the Bell Tower. President John Fry and members of the Temple community honor the nearly 3,000 lives lost, the courage and sacrifice of first responders and members of the military, and the families and communities forever changed by the attacks. The ceremony concludes with 25 chimes and a moment of silence honoring the passengers and crew of United Flight 93, whose actions remain an enduring symbol of courage and sacrifice.
