One day before the city marks 15 years since the September 11th attacks, the FDNY held a special service at St. Patrick's Cathedral on Saturday afternoon to commemorate the members who died that day.
343 FDNY personnel died fighting the flames at the World Trade Center.
127 have died in the years since because of illnesses they contracted during the rescue and recovery effort.
Friday, Police Commissioner Bill Bratton and other top brass marched alongside bagpipe bands in honor the NYPD officers who died on September 11th and in the years after because of those same illnesses.
Active-duty officers and family members of those killed in the line of duty also joined the march through Lower Manhattan.
NY1 spoke with some people from outside the city who came to pay tribute to the fallen.
"My daughter and I decided to come up this weekend and visit the museum," one attendee said. "We had been here when Ground Zero was under construction and had not been back for its completion, so we decided to come up today."
"I saw when the plane actually hit the building. I actually saw it with my eyes, yes," said one woman who saw the attack unfold from Brooklyn. "Don't take me there."
Bratton and Mayor Bill de Blasio also attended a wreath laying ceremony at the Police Memorial Wall.
A memorial service for those killed in the September 11th attacks is also scheduled to take place on Staten Island on Saturday night.
