The Eliza Furnace is an incredibly well-preserved National Register site showcasing Pennsylvania's rich industrial history. Built in 1846, it is one of the few iron furnaces in the United States still with its original heat exchanger piping intact. The furnace is located at the midpoint of the Ghost Town Trail, a 36-mile rail trail that winds through the beautiful Blacklick Creek Valley. Eliza Station is close by, with restrooms, picnic areas, and water fountains.
