Carlisle Fort, also known as Germantown Fort,: 686 or Big Twin Works, is a prehistoric hilltop earthwork located in Warren and Montgomery Counties in southwestern Ohio. It was initially thought to be a defensive structure, and so was referred to as a "fort," but modern archaeologists think it may have served a ceremonial purpose. It was first investigated in 1835,: 174–84 and is most likely of Hopewell origin. Because it is located near Carlisle, Ohio, it acquired the name "Carlisle Fort".
