This charcoal furnace site operated from 1771 to 1883, more than 100 years. It was an integral part of America's industrial revolution before its decline starting in the 1840s. Its inevitable demise was slowed down briefly by the Civil War but the disadvantages of stove casting at the furnace were becoming all too apparent. The biggest disadvantage was that charcoal furnaces had to be near large forests for they had to be fed copious amounts of wood for fuel. The furnaces consumed much more fuel than forests could replenish. Today, the site is well-preserved with 848 acres of land on which historic buildings still stand. You can go on a guided tour or hike around the trails. The park is open daily from 9 AM to 5 PM and no entrance fees.
