The story of Bad Sassendorf's brine goes back millions of years, to when a primordial sea covered much of northern Germany. As it receded, it left behind substantial salt deposits underground. As early as the Middle Ages, this "white gold" was mined locally in saltworks, where brine was boiled down in large pans. Today's Börde-Therme, which first opened in 1976 and was expanded in 1978, has since grown to include a sauna landscape, a wellness area and a sea-salt grotto.
Between 2017 and 2021 the whole facility underwent a thorough renovation, and it now presents itself as thoroughly modern while keeping a cosy, welcoming feel. The brine feeding the pools runs at roughly 3.0 to 3.4% salinity, giving bathers a buoyancy quite different from an ordinary swimming pool. Since the 19th century, this mineral-rich water has drawn visitors seeking rest and quiet in the Westphalian Börde countryside.
