Carroll County, Indiana

Carroll County is a peaceful rural county in north-central Indiana, with the Wabash River flowing through the area. Delphi, the county seat, sits along the river and serves as the center of the county’s historic and community life.

Delphi is home to a section of the historic Wabash and Erie Canal, adding to the area’s rich heritage. Carroll County is also known for its two covered bridges, which become especially scenic during Delphi’s annual Canal Days festival.

Agriculture remains an important part of the local economy, while manufacturing also provides jobs and supports the community. Summers bring lively county fairs and 4-H shows, while the absence of large cities allows the county’s small towns and close-knit communities to stand out.
