Gunpowder works at Kennall Vale is a scheduled ancient monument comprising the remains of a gunpowder manufactory established in the late eighteenth century in the Kennall Valley near Mawnan in Cornwall. The site retains substantial physical evidence of its industrial operation, including stone-built structures, mills, incorporating works, and associated features arranged along the valley floor. The works operated principally during the nineteenth century, producing gunpowder for military and commercial purposes until closure in the early twentieth century. The monument survives as a rare and substantially preserved example of a complete gunpowder manufacturing complex, with the valley's water supply and steep sides having provided ideal conditions for the safe dispersal and containment of explosive production.
