Joanna Furnace Complex
Joanna Furnace Complex, Iron furnace historic district in Berks County, Pennsylvania.
The Joanna Furnace Complex spans 13.8 acres and contains multiple industrial structures including the main furnace building and a blowing engine house.
Samuel Potts and Thomas Rutter III established the iron furnace in 1792, naming it after Potts's wife Joanna, and operated continuously until 1901.
The preserved industrial site demonstrates the evolution of American iron manufacturing techniques from the late 18th century through the Industrial Revolution.
Bethlehem Steel transferred ownership to the Hay Creek Valley Historical Association in 1979, making the complex accessible for educational visits.
The furnace underwent a significant technological modernization in 1889, marking one of the last major upgrades to a charcoal-fired iron furnace in Pennsylvania.
