Twenty-five years after the Sept. 11 attacks, New York City marked the anniversary with a day of remembrance, moments of silence and heightened security in Lower Manhattan.
The anniversary of the 9-11 attacks is now a federally recognized National Day of Service.
The community remembered the 497 Long Islanders killed in the attacks and the continuing toll of illnesses linked to Sept. 11.
The waterfront memorial, featuring two giant postcards, served as a place for families to honor loved ones, lay roses and reflect on those they have not seen in 25 years.
Among the people who have helped keep the Tribute in Light shining is Valerie Webb, who was asked to flip the switch for the first Tribute in Light just six months after the attacks.
More than 9,400 people have died from 9/11-related illnesses.
