A century ago, this dramatic building would have thundered to the sound of clanging hammers and grinding metal. It was one of the busiest tool factories in the southwest, turning out hundreds of chisels, knives, shears and scythes a day. Though it's not quite the industrial powerhouse of yesteryear, it's still a working forge, powered by three working watermills. You can drive or cycle here, or follow a 4-mile (3½-hour) walk east along the Tarka Trail from Okehampton.
