History
Mound House is an archaeological site in the Illinois River floodplain of Greene County, Illinois, with two identified mounds built during the Middle Woodland period and linked to the Havana Hopewell culture. The larger mound, Mound 1, once had a farmhouse built on it by a previous owner, giving the site its name, though the house has since been removed. The property is now owned by the Center for American Archeology. Its archaeological importance was formally recognized when it was added to the National Register of Historic Places on September 1, 1978.
