Visited October 2016: Fort Hawkins (built 1806-1810) in nearby the Ocmulgee National Monument in Macon, Georgia. The US constructed this fort in the historic Creek Nation and was used by the military until 1824. Unfortunately, the Visitor Center was closed (only Sat & Sun Noon-4pm) when we visited. You still have a good view of the fort from outside the fence. I did learn from the signage that the Fort Hawkins blockhouse was reconstructed in 1938 and named for named for Benjamin Hawkins, the General Superintendent of Indian Affairs at teh time. There is ample parking as well and I look forward to seeing it properly later in the future.
