Looking more like a collection of gingerbread houses than an industrial relic, Engelsberg Bruk, a Unesco World Heritage Site in the tiny village of Ängelsberg, 60km north of Västerås, was one of the most important early-industrial ironworks in Europe. During the 17th and 18th centuries, its rare timber-clad blast furnace and forge were state-of-the-art technology, and a whole town sprang up around them. Today you can wander the perfectly preserved estate, made up of a mansion and park, workers’ homes and industrial buildings.
