Fort McAllister Historic Park is a 1,725-acre Georgia state park located near Keller and Richmond Hill in South Bryan County, Georgia and on the south bank of the Ogeechee River. The park is home to the best preserved earthwork fortification of the Confederacy. Though the earthworks were attacked seven times by Union soldiers, it did not fall until taken by General Sherman in 1864 during his famous March to the Sea.
