Axel Ax:son Johnson bought the Engelsberg ironworks in 1916, but found the older works increasingly uneconomical, and closed it down in 1919. Most of the technological, administrative, and residential buildings at Engelsberg Ironworks have been conserved in their original condition. The entire area of Engelsberg Ironworks is explicitly included in the Area of National Interest for Strömsholm Canal established under the federal Environmental Code. It maintains contact with relevant authorities, and ensures that Engelsberg Ironworks is protected and accessible. Engelsberg Ironworks is open and accessible to the public at specific times.
