The Washington Iron Works was Franklin County’s first industry. Established in 1773 by Col. John Donelson, father-in-law of President Andrew Jackson, the iron plantation was acquired in 1779 by Col. James Callaway and Jeremiah Early and expanded to 18,000 acres, becoming one of the last great iron plantations in Virginia. The Saunders family continued the operation until 1850, supplying iron locally and as far south as Georgia.
