U.S. National Memorials are structures or sites established to honor and remember significant events, people, or groups in American history. These memorials serve as places of reflection and education, often featuring inscriptions, sculptures, or plaques that convey their historical significance. Examples include the Lincoln Memorial, which honors President Abraham Lincoln, and the Vietnam Veterans Memorial, dedicated to those who served in the Vietnam War. Many national memorials are located in Washington, D.C., where they attract millions of visitors each year. They are managed by the National Park Service and are part of the broader effort to preserve the nation's heritage and promote understanding of its history.
