Kamp Mound Site is a prehistoric mound-and-village complex along the Illinois River north of Kampsville in western Illinois. Seven surviving mounds, once part of a group of ten, date from about 100 B.C. to A.D. 450 and are tied to the Havana Hopewell culture, which used the place for ceremony and burial. Some are among the largest mounds in Illinois, showing the site’s former scale and importance. A village area dating from about A.D. 450 to 700 indicates continued significance after the main mound-building era. Finds of shell and animal bone fragments and the possibility of a regional trade role further show its broad cultural importance.
