Sala - Helgonmossen

Helgonmossen is part of the large water system that once supplied the Sala silver mine with power.

Hydropower was crucial to silver production, and the expansion of the system is one of the largest of its kind in Swedish history.

Imagine the people who used shovels, spades and carts to shape the landscape to direct the water.

They built embankments of stone and earth, while draught animals carried heavy loads. Each step required careful measurements, calculations and great craftsmanship.

Keeping the mine running required a constant supply of water, which was a challenge. That's why the system was expanded in three stages between the 16th and 19th centuries.

The Helgonmoss Dam was completed in 1822 as part of a new venture led by the mining captain Jacob Henrik af Forselles, who was trying to revive mining after a long economic decline.

Between 1819 and 1822, construction work took place at Helgonmossen and Björnmossen. The landscape was carefully mapped to optimize the flow of water.

The name Helgonmossen has a mysterious history.

Locals used to call it 'Helgsmösa', perhaps to give the name a more colloquial tone - as the real name could bring evil forces to life.

Nature was once seen as animate. Was it a sacred place, or was a dog buried here? Perhaps you'd better follow the folk tradition and say Helgsmösa. At least while you are standing here.
