Remembering those who tragically lost their lives on September 11, 2001, including the fourteen @princetonalumni whom we will #NeverForget. #PrincetonU's Memorial Garden, located just a few steps east of Nassau Hall, includes a bell of remembrance along with fourteen bronze stars set in the ground in their memory. The bronze stars together form a circle, the universal symbol of life and continuity. Each September 11, during memorial services, the bell is struck fourteen times.
