Sullivan County, Indiana

Sullivan County is located in the southwestern corner of the state. Sullivan serves as the county seat and is a classic example of small-town USA. Jokingly, though, it feels like it hasn’t changed much since Eisenhower was president.

Visiting the county feels like stepping into a time capsule of rural Indiana. Life moves at a slower pace, with friendly locals and a strong sense of community that has remained steady over the years.

The Wabash River forms the western border, with Illinois on the other side. The annual Sullivan Rotary Corn Festival is when this otherwise quiet county really comes alive.
