Darien () is a city in and the county seat of McIntosh County, Georgia, United States. It lies on Georgia's coast at the mouth of the Altamaha River, approximately south of Savannah, and is part of the Brunswick, Georgia Metropolitan Statistical Area. It is the second oldest planned city in Georgia and was originally called New Inverness. The population of Darien was 1,460 at the 2020 census, down from 1,975 in 2010. History Colonial period The British built Fort King George in 1721, near what would become Darien. At the time it was the southernmost outpost of the British Empire in North America. The fort was abandoned in 1727 following attacks from the Spanish. Its remains constitute the oldest fort on the Georgia coast. The town of Darien (originally known as "New Inverness") was founded in January 1736 by Scottish Highlanders recruited by James Oglethorpe to act as settler-soldiers protecting the frontiers of Georgia from the Spanish in Florida, the French in the Alabama basin, and the Indian allies of each colonial enterprise. On January 10, 1736, 177 emigrants, including women and children, arrived on the Prince of Wales to establish Darien, which was named after the Darien scheme, a former Scottish colony in Panama. Among the initial settlers was Lachlan McGillivray, who became a noted trader with the Creek people, and Lachlan McIntosh, a leader during the American Revolutionary War. The Scots originated mainly from around Inverness and consisted of both Jacobite and Hanoverian supporting clans, the majority of whom spoke only Gaelic. When visited by Oglethorpe in February, the settlers had already constructed "a battery of four pieces of cannon, built a guardhouse, a storehouse, a chapel, and several huts for particular people." Darien was laid out in accordance with the now-famous Oglethorpe Plan. They showed similar progress in the construction of military forts: by March the Scottish settlers had begun work on two forts, Fort St. Andrews on Cumberland Island, and Fort St. George on the St. Johns River, to the south of the territory claimed by the British government in the Georgia charter. In 1736, the British abandoned Fort St. George by agreement with the Spanish officials in Florida. In 1736 Darien settlers began work on Fort Frederica on St. Simons Island, a few miles south of Darien, between it and Cumberland Island.
