Discover the Cornwall Iron Furnace Tour in Pennsylvania

Step into the heart of America’s industrial past at the Cornwall Iron Furnace Tour in Cornwall, Pennsylvania. This remarkably preserved 18th-century iron-making complex offers visitors an authentic glimpse into the early days of American manufacturing. Operated by the Pennsylvania Historical & Museum Commission, the guided tour leads guests through towering stone buildings, massive casting arches, and original smelting equipment that once powered the nation’s growth.

Why it’s special: Cornwall Iron Furnace is the only surviving intact charcoal cold-blast furnace in the Western Hemisphere. From the roar of molten iron to the rhythm of early industry, this site brings to life the story of Pennsylvania’s ironmasters — centuries before the rise of steel and modern factories.

History/Story of Cornwall Iron Furnace

Founded in 1742 by ironmaster Peter Grubb, Cornwall Iron Furnace became one of colonial America’s most productive ironworks. For over 140 years, it supplied cannon, tools, and pig iron that fueled both the American Revolution and the early Industrial Age. After closing in 1883, the site was preserved as a historical landmark and donated to the Commonwealth of Pennsylvania in 1932. Today, it stands as a rare and beautifully restored testament to early American engineering and enterprise.
