Washington County

Washington County is an administrative division in southern Illinois comprising smaller towns and rural areas shaped by farmland, woodlands, and small waterways. The terrain is gently rolling with Nashville serving as the county seat and scattered unbuilt areas in between.

The area was settled in the early 1800s and formally established as its own county in 1818 from an existing administrative region. This creation was part of the territorial expansion and reorganization of Illinois as new populations moved westward.

The area developed a rural character rooted in farming and local trades, with family and community ties shaping how people lived and worked. Today you can see this heritage reflected in the small towns and farmsteads scattered throughout the county.

Visitors will find mainly small towns with local services and shops, so allow time to explore at a slower pace. Daytime visits work best when businesses and public facilities are open to the community.

A forested area was later converted into a state recreation area that remains open to visitors today. This spot offers a window into the natural landscape of the region away from town centers.
