Legends surround several of the attractions in Barnwell County. The town earned the nickname of "Burnwell" from Sherman's troops. While much was torched, the Church of the Holy Apostles was spared because it was used as a stable for Union horses. The altar window, which depicts the entire doctrine of the Christian church, was taken out and buried before Sherman's troops arrived. The hiding place proved to be a good one.

The story of the Healing Springs, located near Blackville, dates back to the 1700's when Indians believed in the healing power of the springs. Natives of the area still claim the waters as a cure-all for "what ails ya."

The unique vertical sundial in Barnwell is believed to be the only one of its kind in the United States. Although erected two years prior to Standard Time, the sundial keeps within two minutes of that.
