The Miamisburg Mound is one of the two largest conical mounds in eastern North America. Excavations conducted in 1869 revealed details of construction suggesting the Adena culture (800 B.C. to A.D. 100) built the mound in several stages. Listed on the National Register of Historic Places, the mound is 65 feet tall and 800 feet in circumference and contains 54,000 cubic yards of earth. The mound is visible from several miles away because it stands atop a 100 foot high ridge above the Great Miami River. Steps have been built to the top observation platform, where you can enjoy a wonderful view of the area.
