The group is flying the flag in eastern Burke County because it believes the University of North Carolina is trying to hide the toppled Confederate statue, Silent Sam, by placing it inside a building.
The Sons of Confederate Veterans erected the flag to honor those from Burke County who fought in the Civil War.
The organization said it will place huge flags along major highways in North Carolina for every Confederate memorial removed in the state.
“This is our repercussion for this,” Burke Tigers Sons of Confederate Commander Elgie McGallird said. “As long as they keep desecrating and taking our memorials down, we’re going to keep doing what we’re doing.”
