(NEWSER) – Bagpipes opened the ceremony marking the 13th anniversary of Sept. 11, 2001, today in Manhattan, USA Today reports, but in a place transformed by the years. The National September 11 Memorial & Museum sits at the spot where thousands gather to honor the fallen, as the nearly finished One World Trade Center soars overhead.
"It's so symbolic of what the country went through," the sister of Charles Burlingame, the pilot of the plane that crashed into the Pentagon, tells the AP. A mother who lost her son in the attacks also welcomes the new additions. "Surrounding that memorial, Lower Manhattan has been revitalized," she says.
