Explore America’s Industrial Heritage at Cornwall Iron Furnace

Tucked away in the small town of Cornwall, Pennsylvania, the Cornwall Iron Furnace is a fascinating window into America’s industrial past. This remarkable site, founded by pioneer ironmaster Peter Grubb in 1742, is the most intact charcoal-fueled ironmaking complex in the country. From the early 18th century through the late 19th century, Pennsylvania was the beating heart of the nation’s iron and steel industry, and Cornwall played a pivotal role in that story.

Back in its prime, this furnace produced cannons, stoves, and pig iron that supplied the American colonies and even supported the Revolutionary War. For nearly 150 years, men worked day and night to keep the furnace roaring, feeding it charcoal, limestone, and iron ore. The clang of iron and the glow of molten metal were constant until February 11, 1883, when the furnace went out of blast for the final time.
