Accokeek Iron Furnace Marker

The Principio Company constructed the Accokeek Iron Furnace nearby about 1726 on land leased from Augustine Washington (father of George Washington), who became a partner. After Washington’s death in 1743, his son Lawrence inherited his interest in the company and the furnace. When he in turn died ten years later, his share descended first to his brother Augustine Washington Jr. and later to William Augustine Washington. The archaeological site is a rare example of an 18th-century Virginia industrial enterprise. It includes the furnace location, the wheel pit and races, a retaining wall made of slag, an extensive slag dump, and mine pits.
