Mount Horeb Earthworks Complex, Prehistoric earthwork complex in Lexington, United States.
Mount Horeb Earthworks Complex is an archaeological site in Lexington featuring two main sections of geometric earthen structures. The complex includes a circular platform and a surrounding ditch system organized around ceremonial and residential areas.
The site was built by the Adena culture around the time of the first millennium, with structures designed to last for centuries. Archaeological investigations in 1939 uncovered evidence of its ceremonial use through the remains of wooden posts and earthwork arrangements.
The site shows how the Adena people organized labor and designed their ceremonial spaces through carefully built mounds and earthwork systems. These structures reveal the skill and planning that ancient communities invested in their gathering places.
Access requires prior arrangement with the University, so plan ahead before visiting. The site is best explored in dry weather since the earthworks are open to the elements and can become muddy after rain.
One section features an unusual polygonal shape that stretches across the landscape with a deep ditch system running along its perimeter. This irregular design stands out compared to the more common geometric patterns found at other Adena sites.
