The cemetery is the final resting place for the Union prisoners who died while being held at Camp Sumter/Andersonville as POWs. The prisoners’ burial ground at Camp Sumter has been made a national cemetery. It contains 13,714 graves, of which 921 are marked “unknown”.[37]
As a National Cemetery, it is also used as a burial place for more recent veterans and their dependents.[38]
Visitors can walk the 26.5-acre (10.7 ha) site of Camp Sumter, which has been outlined with double rows of white posts. Two sections of the stockade wall have been reconstructed: the north gate and the northeast corner.
