Fort Ancient, near Lebanon, is one of the most beautiful spots in Ohio. The earthen walls built by Hopewell Native Americans 2000 years ago overlook the scenic Little Miami River. Fort Ancient was probably not built as a "fort" for defense. Modern archeological evidence suggests that "Fort" Ancient was a ceremonial gathering place for the Hopewell Indians. The site was used as an astronomical clock by its builders. Certain mounds mark the sunrises of the summer and winter solstices and gaps within the earthen walls mark the minimum and maximum northern moon rises.
