Glen Lean Gunpowder Mills, Clachaig

The remains of several large stone buildings, all contained within a high stone wall. This was one of four large black gunpowder works which operated in Argyll in the 19th century, attracted to the area by its lack of sizeable settlements, its accessibility by sea, and the availability of wood suitable for making charcoal.

Incorporating was the most dangerous operation in gunpowder manufacture, apart from drying. The works was operated by Curtis's and Harvey, which became part of Nobel's Explosives Co Ltd. Latterly it made sporting powder. It closed in 1892. (RCAHMS)
