How many people died on 9/11?
Memorial organizers in Marietta, Georgia, said their Field of Flags event placed 2,997 flags in memory of those who died during the Sept. 11, 2001, terrorist attack. That number is the most specific death toll cited in the reporting reviewed for this story.
Separately, the Fort Walton Beach Fire Department in Florida is inviting 343 members of the public to ring its ceremonial fire bell on Friday, Sept. 11, 2026, in honor of the 343 New York City firefighters who died during the Sept. 11, 2001, terrorist attacks. The bell itself is inscribed with the number 343 for that reason.
Together, those figures show how communities are translating the scale of loss into visible, countable tributes. The St. Louis installation does not repeat a single total headcount in the available reporting, but FOX 2 notes that every flag in the Flags of Valor display represents a fallen service member, paired with a photograph and dog tag.
When and where will the Flags of Valor memorial open in St. Louis?
According to FOX 2, the Flags of Valor tribute is set to open on Art Hill in Forest Park this September, ahead of the 25th anniversary of the Sept. 11, 2001, terror attacks. Volunteers in St. Louis spent a weekend assembling more than 7,500 flags for the powerful display.
FOX 2 also reports that America's Heartland Remembers, a nonprofit, is behind the tribute, which honors heroes and victims of 9/11 as well as service members lost in the war on terror that followed. The first Flags of Valor display took place on the 10-year anniversary of 9/11, and organizers say the installation returns every five years.
Visitors can walk through the display on Art Hill. For more information, FOX 2 directs readers to flagsofvalorstl.com, the event's official site.
Who is building the St. Louis memorial and what does each flag represent?
FOX 2 reports that volunteers from Grimco joined the effort during morning hours, while veterans with Greater St. Louis Honor Flight continued the work later in the day. Together, they prepared each tribute flag that will line Art Hill as part of the memorial installation.
Organizers told FOX 2 that every flag represents a fallen service member and includes a photo and dog tag honoring the individual behind the sacrifice. One volunteer described the display as a moving tribute to people loved and lost.
FOX 2 also notes a logistical milestone: organizers say this will be the final time the flags need to be assembled by hand before being stored for future displays. A separate team will later place photos and dog tags on each tribute with a military escort.
How are other cities marking the 25th anniversary?
In Marietta, hundreds of people marched down Kennesaw Avenue on Saturday morning to plant nearly 3,000 flags at Kennesaw Mountain National Battlefield Park. The Marietta Daily Journal reports that co-chair Justin O'Dell said many flags and materials for this year's event were donated by the City of Marietta, Home Depot, and local businesses, while Withers Tool in Mableton donated labor.
O'Dell told the Marietta Daily Journal that while past project costs ranged from $45,000 to $50,000, the estimated cost for this year's ceremony would have reached six figures without donations. That kind of community underwriting mirrors the volunteer-driven model in St. Louis, where residents are donating time rather than waiting on ticketed events.
In Fort Walton Beach, the fire department's Sept. 11 ceremony will begin at 7:46 a.m. central time, the exact moment the first aircraft struck the World Trade Center's North Tower. The public may stop by Fire Station 6 at 5 Hollywood Blvd. NE anytime that morning or afternoon. Battalion Chief Matthew Baxley said the department honors fellow firefighters who responded despite the dangers and sacrificed their lives for others.

Why do these memorials matter 25 years later?
For participants, the work is about more than preparation. FOX 2 reports that organizers say the St. Louis display serves as a promise that the sacrifices made by service members and their families will never be forgotten. In Marietta, resident and Vietnam veteran Randy White told the Marietta Daily Journal it is important to honor lives lost on 9/11 as well as service members who died in later conflicts.
Volunteer Randy Durham, quoted by the Marietta Daily Journal, said the recognition matters for people who served and for those killed at the World Trade Center. When they fell, Durham said, I will never forget that. It makes me get teary-eyed.
As the nation approaches the quarter-century mark since Sept. 11, 2001, these flag fields, bell ceremonies, and hillside installations turn abstract death tolls into names, faces, and rows of remembrance that visitors can walk through in person.
