Twenty-five years ago, on September 11, 2001, the United States was forever changed. Nearly 3,000 people lost their lives in the terrorist attacks, including the 40 passengers and crew members of Flight 93, whose courageous actions thwarted a planned attack on our nation’s capital.
Today, places across the National Park System help preserve the stories, memories, and history of that day and its aftermath. Along with Flight 93 National Memorial, other national parks, memorials, and historic sites preserve stories of those who responded, served, mourned, and helped communities come together in the days and years that followed.
On this 25th anniversary, take time to remember, reflect, and serve. Visit a national park, learn a story, or volunteer in your community in honor of those who were lost and those who answered the call to serve.
