I was so excited to receive this image from David Frey of an historic round barn in Laurens County; he was gracious enough to let me share it. He made the photograph in 1974, noting that it was a landmark to travelers between Dublin and Wrightsville in those days; the barn is still standing but no longer accessible to the public. As a result, I’m unable to share an exact location. This example is of the octagonal variety and though I have no idea as to a date, my best estimate would be 1900-1910.
A brief review of available references on the subject suggests this may be the only surviving round barn in Georgia; a 14-sided example, the Dorough Round Barn at Hickory Level in Carroll County is listed on the National Register of Historic Places but is apparently in ruins or no longer extant.
