Several of Georgia's ghost towns date from the colony itself. Frederica grew up around Oglethorpe's fort on St. Simons Island from 1736 and had about 1,000 people by 1740; most left after the garrison was disbanded in 1749, and the town was mostly abandoned by 1755. Ebenezer, settled by Salzburger Protestant refugees in 1734, and the seaport of Sunbury, founded in 1758, were both left in ruins by the Revolution. Petersburg, a tobacco town of 1786 where the Broad River meets the Savannah, was for a time Georgia's third-largest town; by 1854 three families were left.
Later towns grew with gold, water power and the Cherokee Nation. The gold rush that began in 1829 made Auraria a boomtown of about 1,000 people before Dahlonega took the county seat. At Scull Shoals, floods and silt from upstream cotton farms made water power unworkable by the mid-1880s; the New Georgia Encyclopedia also blames fires and the Civil War. Union cavalry burned the New Manchester mill in 1864, and the town was never resettled. New Echota, the Cherokee capital from 1825, was emptying by 1834 and abandoned after the forced removal of 1838. What survives ranges from mill walls, earthworks and foundations to a church, a cemetery and a few old buildings. Most of the featured sites are on public land, in a national forest, a national monument, a state park and two state historic sites. Parts of Auraria are private, and Petersburg lies mostly under a reservoir.
