The cross section of the Tower of Voices at Shanksville, Pa., is a “C” shape designed to allow sound to reflect outwardly from the open side in a fan-shaped pattern.
The events of Sept. 11, 2001, left their mark on the nation's psyche, changed the course of its history and produced far-reaching effects that will be felt for years to come.
But 9/11 also left physical marks on the nation's landscape: the memorials in New York, Washington, D.C., and Shanksville, Pa.
In New York, the 9/11 Memorial & Museum, to give it its official title, is located at 180 Greenwich St., the former location of the twin towers.
Conducted by a nonprofit institution whose mission is to raise funds for and operate the site and museum programs, the memorial is a forest of swamp white oak trees with two square reflecting pools in the center marking where the twin towers stood.
The underground museum has artifacts from 9/11, including steel from the twin towers.
This memorial has special meanings for some Butler County residents such as retired Delta Air Lines pilot Scott Kerr of Butler.
Kerr was grounded in Los Angeles because of the ban on flights in American air space in the wake of the attacks.“My attention quickly turned to my sister. She was living and working in Manhattan. Her office was in the shadows of the World Trade Center in the financial district,” said Kerr.Kerr said his sister heard and felt the impacts of the jets hitting the towers but didn't know what was happening until her building was evacuated.<b> A portion of this story is shared with you as a digital media exclusive.
