The forge began in 1814 in an existing cloth mill. It made edge tools for local farming and mining, producing around 400 a day at its peak. After George Finch died in 1885, his widow Rebecca took over the business; under her leadership it reached its most productive and profitable period. Production ended in 1960, but the site reopened as a museum in the early 1970s. On the tour, hands-on tool examples lead into the gallery, working forge and carpenter’s workshop, where the collection shows the range of work behind those water-powered machines.
