Shelby County, Illinois

Shelby County sits in central Illinois, about an hour southeast of Springfield. It’s named after Isaac Shelby, a Revolutionary War hero. Farming drives the local economy, with plenty of corn and soybeans grown across the county.

Shelbyville, the county seat, has a classic Midwest small-town feel. Lake Shelbyville stretches across more than 11,000 acres, surrounded by the Shelbyville State Fish and Wildlife Area. Locals like to joke that there are more boats than people here during the summer.

The Kaskaskia River winds through the county, creating some scenic spots along the way. There’s also a surprising amount of history here. Lincoln practiced law in the old courthouse before going on to bigger things.
