The town of Spa is within walking distance of the campsite. The medicinal properties of the iron and carbonated water from the sources of Spa was already known in the 16th century. In 1764 the first bathing establishment was built and Spa gained fame as a healt resort. In 1774 the first casino of Europe was opened here. In the 19th century Spa was so well known that in English the word "spa" became a generic name for healt resort. The wealthy bourgeoisie came here to build litle castles. Many crowned heads, composers and writers stayed in Spa. "Spa Red" seems to be becoming a generic name for carbonated water. Since 1921 the company Spa Monopole is the exclusive manufacturer of this water, that does not come from the same sources as the ferruginous water.
