Bad Schlema's constituent communities are Oberschlema, Niederschlema and Wildbach.
History
Today's community of Bad Schlema is an amalgamation of the two formerly separate communities of Niederschlema and Oberschlema, which took place in 1958. Since 1994, the community of Wildbach has also been united with this newer community. Both these roughly 800-year-old communities in the Schlema Valley became well known through the centuries for iron, copper, silver and uranium mining. At the time of industrialization, the Toelle, Ehrler, Leonhardt, Rostosky and Philipp factories in Niederschlema and the Wilisch, Leonhardt, Kenzler and Müller companies in Oberschlema were household names throughout Germany. After a means of manufacturing blue dye from cobalt was discovered by Christoph Schürer, there developed in Oberschlema the world's biggest cobalt-blue dyeworks, with 42 buildings. After richradon springs were opened up in the Marx-Semmler-Stolln in Oberschlema between 1908 and 1912, the world's richestradium spa developed after 1918. Only 10 years later, it was counted among Germany's most important spas. Once the uraniummining was taken over by the Soviet occupation forces, the spa, the Radiumbad Oberschlema Hotel, and the downtown of Oberschlema were utterly obliterated. By 1990, the Soviet-German Wismut Corporation had mined more than 80 000 t of uranium from the Schlema Valley and the neighbouring Mulde Valley. After mining came to an end, the mayor, Konrad Barth, organized Schlema's revival as a spa town, which was realized in 1998 when the new Kurhaus was opened. The newly opened radon springs afford ample bathing, now daily used by 1,200 guests at the "Actinon" bathhouse. On 18 January 2005, Saxony's state government bestowed upon the community the official designation Bad, after it had already been recognized as a radon spa since 29 October 2004. Bad Schlema thus became the first community to receive the Bad designation since 1990.
In 2016, the Mayor of Bad Schlema advised the citizens to have their daughters "don’t walk in these areas," referring to streets where underage girls may be harassed in Bad Schlema by illegal migrants.
