September 11: Mixed Reactions From Visitors Attending 9/11 Memorial: 'Some People Forget This Is A Cemetery'

The thirteenth anniversary of the Sept. 11 was remembered at the World Trade Center and National September 11 Museum.

Many people gathered in New York City to honor the memory of those who died during the terrorist attacks. The museum, along with the rebuilt World Trade Center, has received mixed reactions from those who experienced loss during the attacks, according to the Associated Press.

Some who lost their loved ones are upset the place has become a tourist trap.

"Instead of a quiet place of reflection, it's where kids are running around," Nancy Nee, a visitor who lost her brother, firefighter George Cain, during the attacks told AP. "Some people forget this is a cemetery. I would never go to the Holocaust museum and take a selfie."

Others are glad to see life around the place that was once a reminder of their pain.

"When I first saw (One World Trade Center), it really made my heart sing," Debra Burlingame, whose brother Charles Burlingame was the pilot of the plane that crashed into the Pentagon, told AP.

"It does every time I see it because it's so symbolic of what the country went through…I want to see it bustling. I want to see more housing down there, I want to see it alive and bursting with businesses."

CBS reports hundreds of people gathered by the World Trade Center for the reading of the names and the moments of silence to mark when the planes struck the Twin Towers. Nearly 3,000 people were killed at the World Trade Center and the Pentagon.

According to CBS, Joanne Barbara, who lost her husband Gerard Barbara, a FDNY captain, during the attacks, asked those in attendance to continue to support the people who are still dealing with the loss of their loved ones.

“May God bless America, and may we never, never forget,” Barbara said.
