This side of the river was usually called "the mining side", where not many plants grew due to the toxic smoke which contaminated the soil. On the other side of the river, where the smoke did not reach, set many large villas, which made this side to be called "the delightful side". The centre of Falun consists of classical pedestrian streets with small shops. in 1998, the city reclaimed the award of "the city centre of the year" in Sweden.
