Kennall Vale Gunpowder Mills

Entrance to Reserve

A site of great historical interest having a wealth of industrial archaeological features. A great producer of gunpowder for the mining industry from 1812 being one of only two gunpowder works operating in Cornwall at this time. At the peak of its production in the 1860s the company employed over 50 men, and also owned two paper mills, a farm and a number of cottages in the locality. (Relax and enjoy a walk through the woods with only the birds and wildlife for company, and plenty of time to explore.)

Tucked away in a wooded valley near the village of Ponsanooth, the old Gunpowder Works were in operation from the 1800s until the early 20th Century, when they were forced to close due to the invention of dynamite. Today, the remains stand in a nature reserve maintained by The Cornwall Wildlife Trust with its old ruins, beech woods, waterfalls and the Kennall river. Park in the village of Ponsanooth, walk past the shop and up the steep hill. The reserve entrance is on your right.
