Blairsville, the county seat of Union County, incorporated on December 26, 1835 and remains the sole incorporated community in the county. The city remembers Francis Preston Blair, Sr., editor of The Washington Globe.
At the heart of downtown Blairsville is the Historic Union County Courthouse, constructed in 1899, and nearby sits City Hall. Both are on the National Register of Historic Places.
Today Blairsville's town square is frequently the venue for community events. The Old Courthouse has museum exhibits, seminars and concerts provided by the Historical Society. Just south of the square, the society developed and maintains the Mountain Life Museum.
Since nearly two-thirds of Union County is in the Chattahoochee National Forest, Blairsville has earned the official designation as an "Appalachian Trail Community."
