Cass County, Illinois

Cass County is located in west-central Illinois, with Virginia serving as the county seat near the center of the county. The landscape is largely made up of flat farmland, where corn and soybeans are common across the countryside.

Fishing is also a popular activity in Cass County, especially for catfish, which is often featured in local catfish dinners. The Illinois River has played an important role in shaping the area and continues to influence life today, forming the county’s western boundary. Beardstown sits along the river and serves as one of the county’s notable communities.

Beardstown is known for its historic courthouse, where Abraham Lincoln once argued a case. The county was named after Lewis Cass, although he never lived in the area. Today, farmers and river communities continue to make up much of Cass County’s population and character.
