These were near a big spring. A grade up from the Etowah River became known as "the big grade to the shanties", then "Big Shanty Grade", and finally "Big Shanty".The name "Kennesaw" is derived from the Cherokee word gah-nee-sah, meaning cemetery or burial ground.Civil War and afterCamp MacDonald, a training camp, was located there from 1861-1863.During the Civil War, Big Shanty was the site of major fighting in the Battle of Kennesaw Mountain, part of the larger Atlanta Campaign. Kennesaw Mountain National Battlefield Park, located southeast of the city limits, now contains many of these historic areas, though much of the surrounding land has been developed, and some buried artifacts have been taken by people with metal detectors.
