The story so far

from Wikipedia & the U.S. Census

Cahokia Township (T8N R6W) is located in Macoupin County, Illinois, United States. As of the 2010 census, its population was 3,378 and it contained 1,594 housing units.

Between the 2010 and 2020 censuses its population fell from 3,378 to 3,151 (-7%). Half of its homes were built before 1950.

Wikipedia doesn’t have a history of Cahokia yet — the old photos, dates and memories neighbors add here are how it gets written.

Nothing in Cahokia is on the National Register yet

That’s true of most small towns. It doesn’t mean Cahokia has no history, only that no one has written up a nomination. The closest listed place is Route 66, Litchfield to Mount Olive in South Litchfield, 3.3 miles away.

How a place gets listed

1Talk to the stateEvery nomination goes through the State Historic Preservation Office. Owners, towns and historical societies can start one.
2Try a local or state list firstMany states keep their own register with a shorter form, a common first step for old barns, halls and schoolhouses.
3Write it upA nomination covers the history, photos and a map. Route 66, Litchfield to Mount Olive’s page links to a real one.
Know an old place in Cahokia?A mill, a schoolhouse, a cellar hole, a church: add a photo of it to Cahokia’s story, or a memory of it.
