About halfway between downtown Chillicothe and the Adena Estate stands the Story Mound, preserved by the Ohio Historical Society near the corner of Allen and Delano Avenues. It closely resembles in size and shape the now-lost Adena Mound: originally 25 feet high and 95 feet in diameter.

From the same period, it probably matches its more famous former neighbor in function as well: Excavations at the Adena Mound in 1897 [see: Adena] uncovered the burial of a young man, plus a set of postmolds, forming a ring. This pattern was the first evidence of the round structures, built to enclose funeral rituals, that lie under Adena mounds.

This building (or fence) was about fifteen feet across, and was ritually dismantled or burned after its use, and buried under the mound.
