New Tower at Flight 93 Memorial Honors 9/11 Heroes

The Tower of Voices is arguably the most dramatic of Murdoch’s interventions, symbolically towering 93 feet like a steeple. Within the confines of the memorial’s precast columns, which are clustered together like a group of reeds, are the aluminum chimes, each between five and 10 feet long. Each chime (the largest weighing up to 150 pounds, according to a press release) is specially tuned to create a unique tone (Arup provided both structural and acoustic expertise). In concert, these instruments create a rich, resonant melody as the wind moves among them. Visitors are able to pass beneath to gaze upward at the chimes, or out to a grove of white pine, serviceberry, hawthorn, and redbuds.
