Fort McAllister State Park is a 1,725 acres (698 ha) Georgia state park located near Keller and Richmond Hill in south Bryan County, Georgia and on the south bank of the Ogeechee River (some parts of the park border the Atlantic Ocean). It is roughly ten miles south of Savannah. The park is home to Fort McAllister, the best-preserved earthwork fortification of the Confederacy. Though the earthworks were attacked unsuccessfully seven times by Union soldiers, it did not fall until it was taken by General Sherman in 1864 during his March to the Sea. The park, located on the coast, is nestled among giant live oaks and a large salt marsh. In addition, the park contains a museum specializing in Civil War artifacts. The fort was added to the National Register of Historic Places in 1970.
