8-44 Olive Furnace

Side A: Olive Furnace in Lawrence County was one of 83 blast furnaces in the Hanging Rock iron-making region of southern Ohio and northern Kentucky. John Campbell (1808-1891), the “Father of Ironton,” and others established the furnace in 1846. The base of the furnace is carved out of rock and supported by Roman style arches. Only one of these arches remains some 170 years later. The furnace became a stop on the Underground Railroad. Conductors ushered escaping slaves through the area to points further north. The Olive Furnace was the last charcoal furnace to operate in Lawrence County. After seven decades of service, the furnace was sold and dismantled for scrap in 1915. Olive Furnace was listed on the National Register of Historic Places in 2007.
