Help finding Gatlinburg/blue ridge pkwy area civil war site

When I was a kid, we always used to visit this civil war site when we’d go to the smokys. We never stayed in one place for more than a day or two, we would stay in Cherokee, Maggie Valley, Gatlinburg, etc. So I don’t even know if this place was actually near Gatlinburg. From my research there’s nothing around there that I’m describing. I just remember there were some stone structures and old cannons. As a kid it seemed like a huge open area. But that may not be correct since it’s been 30+ years. I feel like it was a battlefield but I really don’t remember much more than vague details. Can anyone suggest anything that it may be and I’ll look it up to see. I’d like to take my boy this summer to some civil war era attractions. TIA
