The remains of a dye mill stand at the base of Tower Bank in Wooler. It was a pan-tiled building at the bottom of the road. There trade of dying was first recorded in Wooler in 1296. There are two grouped ranges arranged at right angles to each other: one a two-storey dwelling, or {mill keeper's cottage HER 24073}; the other the former water-powered dye mill, fed by a leat from Wooler Water. The dye mill is shown on the first edition Ordnance Survey of c.1860 but would have gone out of use when the steam laundry was built in the 1890s. The buildings fell into disuse in the 1960s. A development scheme on the site in the 2020s proposes to stabilise and conserve the dye mill.
