Around 100 years ago, there was a whole community here at Karlsfors. There was a bank, a post office, a school and a store. The industrial community started with alum production as early as in the 18th century. The alum was for example used as an ingredient for red paint. In the middle of the 19th century the industry shifted to mainly produce lime for cement and soil improvement. Today you can only see the remains of the industry.
