Emerald Mound and Village Site


The Emerald Mound and Village Site is a pre-Columbian archaeological site located northwest of the junction of Emerald Mound Grange and Midgley Neiss Roads in St. Clair County, Illinois. The site includes five mounds, two of which have been destroyed by modern activity, and the remains of a village. Middle Mississippian peoples inhabited the village, which was a satellite village of Cahokia. The largest of the mounds is a two-tiered structure that stands high; its square base is across, while its upper tier is across. At the time of its discovery, the mound was the second-largest known in Illinois after Monks Mound at Cahokia.
The site was added to the National Register of Historic Places on October 26, 1971.
