Four years have passed.
Four classes of seniors have graduated and said their good-byes to the campus that was rocked on Sept. 11.
But four years later, the students at UNC - who were in high school when the U.S. was attacked by terrorists - continue to operate in the spirit of unity started by the students who have come and gone.
"That night on college campuses, millions and millions of students and faculty across the country came together in solidarity," said Margaret Jablonski, vice chancellor for student affairs, during a memorial event held Sunday.
About 100 students came together Sunday night on Polk Place for the memorial service, sponsored by Committee for a Better Carolina and the Foundation for the Defense of Democracies.
Those attending the service sat in front of thousands of American flags, representing the almost 3,000 that died in the attacks.
"Just by having the representation of flags shows (students) still care about the individual lives that were lost," Jablonski said. "It does still touch us."
Many University community members chose to remember the day by gathering in Memorial Hall Sunday for "Carolina Performs," a student arts celebration during the building's grand opening weekend.
Bernadette Gray-Little, dean of the College of Arts and Sciences, said the arts are one way for individuals to remember the tragedy.
