The eventful history of Billnäs is almost 400 years long. The previously prosperous ironworks has taken a step back and given room for modern industry. Today it has become an idyllic village admired by tourists. The past is, however, very much present in Billnäs: the oldest residential and commercial buildings in the village are from the 1700s, and the old craftsmanship still thrives. Several entrepreneurs representing different industries serve the residents and tourists in the village. https://www.visitraseborg.com/en/see-and-experience/castles-villages/billnas-village/
