Lupeni (German: Schylwolfsbach, Hungarian: Lupény) is a town in Hunedoara County in the Transylvania region of Romania.
After 1840, mining led to a massive change in the population and economic structure; miners from many nations immigrated. From 1881, coal deposits were exploited industrially; large workers' settlements were created.
After the Second World War, the mines in the area surrounding the town were Romania's most important coal suppliers.
The one-sided economic focus on mining led to high unemployment after the 1989 revolution, when some of the mines were closed. Since then, trade, forestry and tourism have played an increasing role.[3]
