Abundant resources like trees, iron and water brought men to live and work near Pine Grove Furnace State Park. After the iron industry went bankrupt in the late 1800s, the area was left as an unattractive industrial wasteland. Now, parts of the iron industry are preserved to tell an important story of the early years of our nation. Through thoughtful and visionary restoration of the natural resources, Pine Grove Furnace is preserved as a state park that is free for you to enjoy.
