Stone stores, a furnace house and waterworks survive at Bonawe, where timber from Argyll once fed a charcoal-fired blast furnace. Bonawe Iron Furnace, also called Lorn Furnace, is an 18th-century industrial complex for making pig iron, the raw iron cast from a furnace before further working.

Built by the Newland Company in 1753, it linked local woodland and river power with Cumbrian capital, ore and markets. Its closure in 1876 reflects the shift from charcoal ironmaking to coke-fuelled industry.

What follows is drawn from published sources, with each claim labelled by how firmly it is established.

History

Bonawe Iron Furnace was built in 1753 by Richard Ford's Newland Company.

The site was chosen for local wood for charcoal and river water to power a water wheel.

Most building materials came from Cumbria, where the company was based.

The furnace could be run almost continuously for nine months at a time after being brought up to temperature.

At its height the operation employed up to 600 people, most involved in timber collection and charcoal production.

Most pig iron was taken to the Newland Company offices in Cumbria for shipping or further processing.

The rise of coke-fuelled ironmaking made Bonawe less profitable in the 19th century.

The furnace closed in 1876 and is now a scheduled monument managed by Historic Environment Scotland.
