Named for King George I of England, the fort was a typical small European field fort consisting of a triangular earthwork-walled enclosure. Surrounded by a moat on two sides and the north branch of the Altamaha River on the third, the fort's main defense was a 26-foot square blockhouse. A log palisade stood in the moat to deter enemy soldiers and Indians from storming the fort from the land side. Several palmetto-thatched huts, a barracks and an officers' house also stood within the fort. The blockhouse at Fort King George is a duplicate of the original structure.
Future plans call for reconstruction of the barracks and other small structures.
Long after the fort was abandoned, sawmills were erected on the site, eliminating traces of the fortifications. Adjoining the fort is one of the oldest British military cemeteries in the southeastern United States. The cemetery contains 65 graves including 17 marked as the final resting place of British soldiers serving at Fort King George. A living history portrayal of early 18th century life at Ft.
