Four in ten were never found
Why the site is sacred
For the families of those 1,100, the site is where they come to remember. That shapes how the museum manages the grounds and how it ensures that family members have access.
The anniversary
On the anniversary, the day belongs to them. They are the only ones who speak, they stand at center stage reading the names of their loved ones, and they are the only ones admitted to the museum that day.
The names are read in alphabetical order, so the first one every year is Gordon A. Amoth Jr.
White roses
A florist in the neighborhood, Mikey Flowers, donates white roses to the museum. A white rose is placed next to the name of every victim on their birthday.
Why were so many never found?
The collapse of the towers pulverized concrete and other materials, and fires on the pile burned for 99 days, ending on December 19, 2001. New York City's medical examiner recovered more than 21,000 pieces of remains, many of them very small. Identifying a person from a fragment depends on matching its DNA to a sample from the person or a close relative. Some fragments were damaged beyond what the methods of the time could read.
How is the medical examiner still identifying victims?
The medical examiner's office never closed the 9/11 identification effort, and it retests remains as DNA technology improves. Newer methods can read heavily degraded samples that earlier tests could not. The office has announced new identifications over the years, some of them more than two decades after the attacks. Remains that are still unidentified are kept in a repository at the museum's bedrock level, under the medical examiner's care.
How are names arranged on the memorial?
The names on the memorial's bronze parapets are not in alphabetical order. They are arranged by meaningful adjacencies, which place people next to the colleagues, friends, and relatives that families asked them to be beside. Employees of the same company, members of the same firehouse, and passengers on the same flight were grouped together.
