Used as a bank for over 80 years, it now serves as the visitors’ center for the town. The building is a National Historic Landmark and part of the Grinnell Historic Commercial District.
Blast Furnaces at Scranton, Pennsylvania
The stone blast furnaces in a park just outside of downtown Scranton are an imposing reminder of this Pennsylvania city’s early industrial history. George and Selden Scranton had owned an iron furnace in northern New Jersey before moving to Pennsylvania. In 1840, they and their partners built an iron furnace in Slocum Hollow on the Roaring Brook. Their enterprise, later renamed the Lackawanna Iron and Steel Company, grew to become one of the largest producers of iron in the United States. At the turn of the twentieth century, however, the company moved its operations to New York. The mills and other buildings were demolished, leaving only the four blast furnaces behind.
