Joanna Furnace

Nestled in an area rich with iron ore, abundant woodland for charcoal, limestone, and waterways to provide power, lies Joanna Furnace -- a historic remnant of Berks County's thriving early iron industry.  Unlike today's corporations with their large buildings and complex hierarchies, the 19th century iron industry at Joanna Furnace was the product of rugged individualism. From the semi-wilderness of Robeson Township, in 1791, Joanna Furnace was started by Samuel Potts, Thomas Rutter III, Thomas May and Thomas Bull. The furnace was named in honor of Pott's wife Joanna Holland Potts.

Visit Joanna's new Cast House and visualize the smoke, dust, and motion of an iron furnace in operation. On this site from 1791 until 1898 workers produced pig iron and iron products utilizing Pennsylvania's magnificent natural resources. In peacetime and during wartime, the furnace sought to supply the needs of a growing nation.

Today the site welcomes visitors to tour the original buildings or participate in a rich schedule of special events
