Strömstad soon established itself as an important shipping town and during the great herring fishing period in the second half of the 18th century, trade flourished. Salted herring, dried fish and wood were important commodities and several large merchant vessels had their home berths in Strömstad. At this time, when herring was being fished like never before, the foundations were laid to what would later become Strömstad’s main identity, the spa town. Strömstad is one of the oldest spa towns in Sweden. People were ‘taking the waters’ at the spring Lejonkällan in1782. The spring’s mineral rich water was thought to cure ills like epilepsy, paralysis, rheumatism etc. Water cures were fashionable at this time and outdoor activities in combination with taking the waters were seen as very beneficial to health. A number of open-air baths and indoor baths were built in Strömstad in the following century. The old baths had features like shower-baths, mud-baths, tub-baths and seaweed baths, treatments that are still highly topical today and that are also on offer in our present baths, built in1909. After having been without an open-air bath for a few decades, Strömstad has again an open-air bath, opened in 2005.
