Greensboro, the county seat of Greene County, first chartered in 1786. The city, spelled "Greensborough" at the time, holds the distinction as the first town in America to be burned to the ground and its inhabitants killed by Native American Indians. The city later incorporated on December 10, 1803.
Greene County's courthouse, constructed around 1848, is listed on the National Register of Historic Places. Other historic monuments include the Iron House, a massive 2,000-pound structure and the "Gaol", a Bastille-like jail that is one of the oldest penal structures in Georgia.
