The wadmal stamp-mill was probably built in the mid-nineteenth century and used to pound woollen material to make wadmal. The building is cog-jointed using pine logs and covers a ground area of approx. 3 x 4 metres. The roof is covered with birch bark and turf. Inside there are large wooden containers, into which were placed the woollen material and hot water. Large wooden hammers driven by the water-wheel moved up and down, pounding the material in the containers. There may have been eight stamp-mills of this type in Bardu. The reconstruction of this wadmal stamp-mill was completed in 2004.
