Within a cemetery enclosed by iron fence and gates dating to 1912 stand two hundred six marble grave markers placed in 1890 by citizens of Georgia to replace original hand-carved wooden markers. In 1904, the Robert Patton Chapter 445, United Daughters of the Confederacy® purchased the cemetery and cared for it until it was formally presented to the federal government on 5 June 1932. Non-invasive ground-penetrating radar has located two hundred sixty-seven sets of remains of people who died in the prison camp from 1862 to 1865. These remains are watched over by The Lookout, a bronze statue created by Confederate States veteran Sir Moses Ezekiel and dedicated in 1910. Two hundred fifty-three Confederate officers and enlisted men who died in the prison have been identified, although some sources indicate that more than three hundred died while imprisoned on the island. The work was done using the best available scientific methods and primary resources at the time, while leaving fuller reconciliation of the information to future generations and future technology.
