The slitting mill was a water mill used for slitting bars of iron into rods. It is likely to have been invented in Liege, Belgium; the first one in England was built in Kent in 1590.
Until 1703, Ambrose Crowley was relying on mills in the Midlands, but when he decided to build his own, the fast-flowing River Derwent in the valley below Winlaton provided the perfect site.
