Who built the Mound and why did they build it?. Miamisburg Mound State Memorial. , The mound is thought to belong to the Adena culture because of its conical shape and the character of the burials said to have been found within it. Adena mounds, unlike those built by the Hopewell culture which followed them, tended to be conical in form. The Adena culture was named for the Adena Estate in Chillicothe, the home of Ohio's sixth governor, Thomas Worthington.

The Adena culture arose in the Ohio River Valley by about 1,000 BC. As the first people in the region to domesticate plant foods such as squash and sunflower, they lived in semi-permanent settlements composed of two to four cone-shaped bark structures located near streams.

The Adena peoples were among the first to make pottery in what is now Ohio. Adena pots as large as eighteen inches high and twelve to fourteen inches in diameter have been found. They made a wide assortment of tools from bone and flint to assist them in their daily occupations. Their principal hunting tool was the spear. They fashioned beautiful and often abstract works of art, such as tubular smoking pipes made from stone or clay. They adorned their bodies with copper, shell, and slate ornaments; rings, bracelets, and necklaces. They also carved stone tablets with elaborate, abstract designs. The Adena were the first in Ohio to build earthworks and burial mounds. Elaborate funeral ceremonies evidently were developed during which they buried their dead beneath earthen mounds, which grew in size over time. Square or rectangular log tombs sometimes enclosed bodies within the mounds.
