Neabsco Iron Works

The Neabsco Iron Works (alternates: Neabsco Company; Neabsco Iron Foundry ) were located in Woodbridge, Virginia, US. After abandoning the Bristol Iron Works,John Tayloe I established the Neabsco Iron Foundry around 1737. The business became a multifaceted antebellum industrial plantation. Its activities included farming, leatherworking, milling, shipbuilding, shoemaking, and smithing, as well as supplying raw materials used as weaponry during the American Revolution. The business grew and expanded with his son, John Tayloe II, when, in 1756, he bought the Occoquan Ironworks company, eventually running it as one business with the Neabsco. It was situated on 5,000 acres (2,000 ha) by the Neabsco Creek.

The Neabsco Iron Works were the first Iron Works in Northern Virginia. Established around 1737, By John Tayloe I, a wealthy Virginia land owner, who owned several iron works, his son, John Tayloe II was a partner in the nearby Occoquan Iron Works. The site offered 3–5000 acres of trees for firewood mostly to make charcoal to heat the blast furnaces. It also offered large deposits of iron ore. A Creek with lots of running water and adequate fall for water works to operate bellows and mills. As the site is situated at the cusp of the fall line and coastal plain, the creek was deep enough in part, to transfer pig iron (recently blasted raw unworked iron) by boat less than a mile downstream to Neabsco Harbor on the Potomac River. There the iron could be transferred to ocean-going vessels. It was also close to a major road, the Kings Highway. Because much of the ore, on site, turned out to be of low quality, ore was boated in from Tayloe's mines in Maryland. Most of the labor was provided by slaves and indentured servants. The works shut down around 1820 as it couldn't compete with cheaper iron being produced in the North and had exhausted its supply of abundant, available fire wood. It is estimated that it took one half an acre of firewood to produce one ton of pig iron.

Today little remains of the Neabsco Iron works; the forest has reclaimed the slopes. There are some pits, some stones of the furnaces and foundations of buildings. There are also intact service roads and road remnants, eroded water races and terraced work areas on the slope above the two furnaces locations. Slag from iron blasting litter the terraced work area on the slope above the furnaces. The Creek and Neabsco Harbor are now silted in due to deforesting for tobacco farming and rampant development upstream.
