About Nilwood

Nilwood is an incorporated town in Macoupin County, Illinois, United States. The 2020 census counted 201 residents. Illinois Route 4 passes through the north side of town, leading southwest 11 miles to Carlinville, the county seat, and northeast 4 miles to Girard. The town is drained to the northeast by the headwaters of Shearles Branch, which turns south and flows to Macoupin Creek, a west-flowing tributary of the Illinois River. Nilwood makes sense once you see how its past, landscape, and current gathering spots overlap. The useful thing to know about Nilwood is that its older landmarks and current settings belong to one connected place.
