Cadiz

History

Cadiz was founded in 1803 at the junction of westward roads from Pittsburgh and Washington, Pennsylvania, and named after Cádiz, Spain. The town became the county seat of newly formed Harrison County in 1813. By 1840, Cadiz had 1,028 residents; by 1846, the town had four churches and 21 stores. The Steubenville and Indiana Railroad, a predecessor of the Pennsylvania Railroad, opened to Cadiz June 11, 1854. In the early and mid nineteenth century, several local families operated stations and served as conductors in the Underground Railroad, helping runaway slaves escape to Canada. Coal mining, both underground and surface, became the prominent industry through most of the twentieth century. More recently the development of the Marcellus Shale in the surrounding area has made Cadiz a center for natural gas production. The MarkWest Complex, opened in 2012, processes more than 180 million cubic feet of natural gas per day for shipment via pipeline to Mont Belvieu, Texas.
