Fort Hill Serpentine Enclosure in Highland County, Ohio

The massive earthwork at Fort Hill is entirely made of stones. The wall itself ranges from 6 to 15 feet in height, averages 30 feet wide at its base, and encloses 35.3 acres. It follows the natural contour of the rim of the hill and is bordered on the inside wall by a substantial ditch.

Fort Hill was constructed to represent a serpent that can be seen at the top where their heads come together.

The stone walls undulate like a Serpent the extent of the works. Fort Hill is not maintained and there not even a sign to direct you up the hill. If you go in the summer, you will not be able to see anything.
