Trummelsberg, Industrial heritage site in Västmanlands län, Sweden
Trummelsberg is an industrial heritage site in Västmanlands län where the remains of an ironworks lie scattered across a forested landscape near Lake Åmänningen. Stone pillars, roasting furnace foundations, and stone piers mark where production once took place.
The ironworks began operations in 1622 and continued for nearly three centuries until closure in 1907. During its long run, it became a major industrial center in the region.
The industrial works formed a complete settlement where workers and their families lived in housing built nearby, with shops and schools serving the community. Walking through the site today reveals how deeply the works shaped daily life in this region.
The site is best visited by car from the nearby town of Fagersta, and sturdy shoes are recommended since paths wind through uneven ground and stones can be slippery. The forested setting means weather can change quickly, so checking conditions beforehand is wise.
The remains include about 60 large coal house pillars made from slag brick, a byproduct of iron production left standing on the site. In recent years, roughly half of these pillars have been restored to show what they originally looked like.
