Hopewell Furnace was established as a National Historic Site on August 3, 1938 and preserves the late 18th and early 19th century setting of an iron-making community, including the charcoal-fueled furnace, and its natural and cultural resources.  This community illustrates the essential role of industrialization in the growth of the early United States.  The furnace was established in 1771 by Ironmaster Mark Bird and operated as a furnace for the next 112 years. 

The park’s facilities are currently open Wednesday through Sunday, 9:00 a.m. to 5:00 p.m.  Hopewell Furnace is located at 2 Mark Bird Lane, Elverson, PA 19520 about five miles south of Birdsboro, PA, off Route 345.  Admission to the park is free.  For more information, call 610-582-8773 or visit the park's web site at www.nps.gov/hofu
