Kengis' Iron Manufacturing Facility was once founded by Arendt Grape. Kengis was the northernmost Iron Manufactoring Facility in the world. A hammer shop was completed in 1649, and the jacket iron used was obtained from the blast furnace at the Vittang iron mine. Kengis also processed copper from the Svappavaara mine.
Sweden's northernmost ironworks mansion was built around Kengis. During the Great War of 1717, the Russians burned Facilities, but it was rebuilt. At its largest, it had 120 employees and 500 inhabitants. Kengis ceased operations in 1879 after being destroyed by fire. The old buildings are still reminiscent of the old days.
At the same time, the power plant built on the edge of the rapids in 1952 is the smallest and newest of them.
