Hopewell Furnace National Historic Site, Elverson, Pennsylvania

Hopewell Furnace showcases an early American industrial landscape from natural resource extraction to enlightened conservation. Operating from 1771-1883, Hopewell and other "iron plantations" laid the foundation for the transformation of the United States into an industrial giant. The park's 848 acres and historic structures illustrate the business, technology and lifestyle of our growing nation.
