The purpose of the Vietnam Veterans Memorial was to honor all who had served, with a special tribute – their names engraved – for those who did not return.

The Vietnam Veterans Memorial stands as a symbol of America's honor and recognition of the men and women who served and sacrificed their lives in the Vietnam War. Inscribed on the black granite walls are the names of more than 58,000 men and women who gave their lives or remain missing.
