History
Franklin Furnace takes its name from an iron furnace that operated in the area during the 19th century, when the Hanging Rock Iron Region of southern Ohio and Kentucky was one of the most productive iron-producing areas in the United States. The abundant hardwood forests and local iron ore deposits made communities like Franklin Furnace vital contributors to the region's industrial output in the pre-Civil War and Civil War eras. As iron production declined in the late 1800s, the community transitioned to a more agricultural and residential character while retaining the historical identity embedded in its name.
