Most buildings are gone leaving a network of 38 miles (61 km) of once-paved roads and trails in a wooded three-square-mile (7.8 km2) area. The surviving building housing the "brig" today hosts a museum featuring displays that depict the activities and lives of the hundreds of thousands of Navy and Air Force personnel as they trained to go to war at Sampson.
