In the 20 years since the September 11, 2001, terrorist attacks, Americans have gathered on the anniversary to remember the nearly 3,000 people who died in New York, Virginia and Pennsylvania, as well as the first responders who put their lives on the line to save victims.
Here’s a glimpse at how first responders around the United States have commemorated their lost colleagues over the past two decades.

In Long Beach, California, city officials, firefighters, police personnel (pictured here) and members of the community observed a moment of silence on September 11, 2019.

The Patriot Flag — which honors the military, first responders and families of the victims of 9/11 — is raised on a fire truck ladder at Arlington National Cemetery in Virginia in 2011. The flag flew in all 50 states over 50 weeks to mark the 10th anniversary of the attacks.

In Philadelphia, a sailor walks past a flag aboard the USS Somerset in 2014. The ship is named for the Pennsylvania county where Flight 93 crashed after it was hijacked September 11, 2001. It was the last of three vessels honoring the attacks’ victims and first responders. Two other ships, the USS New York and the USS Arlington, are named for the cities that were attacked.
