Andersonville National Cemetery was established to provide a permanent place of honor for those who died in military service to our country. The initial interments, beginning in February 1864, were those who died in the nearby prisoner of war camp. Today the cemetery contains nearly 20,000 interments. Administered by the National Park Service, Andersonville National Cemetery uses the same eligibility criteria as cemeteries administered by the National Cemetery Administration of the Department of Veterans Affairs (VA).
