About Andersonville Prison
Andersonville Prison (Camp Sumter) is the Confederate-era prisoner-of-war camp near Andersonville, Georgia, now preserved as a national historic site and cemetery. The camp operated during the final year of the American Civil War and is a central site for Civil War remembrance.
The preserved site includes the marked outline of the stockade, interpretive exhibits and the Andersonville National Cemetery where thousands who died at the camp are buried. The onsite National Prisoner of War Museum broadens interpretation by placing Andersonville within the longer history of captivity and wartime detention.
Interpretive walks and markers explain the camp’s layout, living conditions, and prisoner experience; the cemetery and monuments are focal points for commemoration.
Camp Sumter opened in February 1864 and was used until May 1865 to hold Union prisoners; overcrowding, shortages of food and disease led to very high mortality. The camp’s commandant, Henry Wirz, was tried and executed after the war for war crimes related to conditions at Andersonville. The site was later designated and developed as a national historic site and cemetery to preserve memory and interpretation.
The site lies adjacent to the small town of Andersonville in rural Sumter County, Georgia, and is located in south-central Georgia, roughly a two-hour drive from the Atlanta metropolitan area.
- Dates and scale: Camp Sumter was active from February 1864 to May 1865 and held tens of thousands of Union prisoners under extremely crowded conditions.
- Cemetery: Approximately 13,000 prisoners who died there are interred in the national cemetery on site, making the cemetery a principal focus for visitors.
