Cadiz, OH

Cadiz is Harrison County’s seat, founded in 1803 where roads from Pittsburgh and Washington, Pennsylvania, met. The village took its name from Cádiz, Spain, and by 1846 it had four churches, 21 stores, and a population of 1,028. That early road junction gave Cadiz a practical reason to be there; county government later made the village the place where the wider Harrison County story comes together.

Cadiz’s history has several layers. Manufacturing and farm processing shaped the nineteenth-century town, and the village became part of the Underground Railroad during the Civil War. Coal mining—both surface and underground—became the major twentieth-century industry. The Puskarich Public Library’s main branch is on East Market Street, while Harrison Hills City School District serves area students through its elementary and high school campuses. More recent energy development has added Utica and Marcellus shale facilities around the county. Cadiz remains a courthouse village with an old crossroads layout, a public library, and an industrial history that runs from farm goods to coal to shale.
