The Carlisle Iron Works Furnace in Boiling Springs was built in 1760 and remains in excellent condition. This is one of the earliest blast furnaces and was founded by John Rigbie & Co. It was operated by Michael Ege, a well-known iron master, after 1781.
A marker located on PA 174 just east of Boiling Springs reads: "Founded about 1762 by John Rigbie and Co. Operated after 1781 by Michael Ege, noted ironmaster of the period. Ruins of the charcoal furnace still stand."
Please note: The iron furnace is located behind the Grist Mill.
