F.D. Roosevelt State Park is a 9,049 acre (35.91 km²) Georgia state park located near Pine Mountain and Warm Springs. The park is named for former U.S. President Franklin Delano Roosevelt, who sought a treatment for his paralytic illness in nearby Warm Springs at the Little White House. The western portion of the park, formerly named Pine Mountain State Park, was named a National Historic Landmark in 1997. F.D. Roosevelt State Park is Georgia's largest state park.Several structures in the park were built by the Civilian Conservation Corps in the Great Depression, including a stone swimming pool and Roosevelt's favorite picnic spot at Dowdell's Knob, overlooking the valley below. President Roosevelt would take polio patients suffering from depression along on picnics at Dowdell's Knob.HistoryThe region containing the modern-day park was inhabited by the Creek Nation until ceded under the Treaties of 1825 and 1826, which granted the territories between the Flint and Chattahoochee rivers to the State of Georgia. An influx of settlers established the town of Kings Gap, named after King's Trading Post located near the modern-day Liberty Bell Pool. The town eventually vanished by the 20th century.
