Cass County

Cass County is an administrative district in western Illinois positioned between the Illinois and Sangamon Rivers, characterized by rolling farmland, woodlands, and scattered communities. The landscape combines open countryside with small towns that form the backbone of the county's geography.

Cass County was established in 1837 when it separated from Morgan County and took its name from Lewis Cass, a military officer of the early 1800s. This founding shaped the territory's development as a rural administrative hub.

Small towns and villages throughout the county shape daily community life, with residents gathering for local events and celebrations that reflect rural traditions. These gatherings reveal how agriculture and family roots remain central to how people here spend their time together.

Virginia, the county seat, houses the main administrative offices and serves as the central hub for government services. Visitors can find local information and services there for understanding how the county operates.

The Meredosia National Wildlife Refuge extends partially into Cass County and provides habitat for wildlife along the Illinois River. These protected areas make the region important for observing bird species and other animals.
