There was a time when people did their best to avoid western Germany's Ruhr region, best known as a decaying industrial area dominated by coal mines and blast furnaces. But now the area is enjoying a "green" transformation that is powering a tourist boom. A number of former industrial sites have been transformed into centers for business, entertainment, and tourism.
