Bad Aachen Bathing Tradition


Water Analysis

The main components of mineral thermal water of the “Rosenquelle” spring are:
Sodium (Na), Chloride (Cl) and hydrogen carbonate (HCO3).


The Aachen mineral thermal water has a healing effect at the following complaints:

  • rheumatic diseases
  • degenerative disorders
  • inflammatory and degenerative diseases of the musculoskeletal system
  • rehabilitation after accidents and operations
  • gout and osteoporosis
  • dermatosis




For more than 2000 years the hot springs of Aachen have been well known and up to today inseparably connected with history and the name of the town. The name Aachen can be derived from the Old High German word “ahha” (Water) as well as from the early medieval “Aquisgrani“ and from Latin “Aquae granni“ derived from this, which again refers back to the saviour god “Grannus”.

After Celts and Teutons it were first of all Romans who found out about the healing and alleviating effect of the Aachen springs and celebrated a holistic therapeutical concept of bathing culture. Already at that time bathing in hot mineral thermal water had not only health reasons. It was courteous to meet each other in the bath house and on this occasion also discuss important business affairs. Under the reign of Charlemagne, who himself was so deeply convinced of the hot spring’s healing effect that at the end of the eights century he declared Aachen his favourite palatinate; Aachen’s bathing culture again experienced a heyday.

Thanks to the activities of the Belgian spa doctor “François Blondel” Aachen, from the 17th century, became one of the most famous spa resorts. Prominent spa guests from all over Europe – e.g. Tsar Peter the Great, the composer Friedrich Händel, the Prussian King Frederic the Great, King Gustav II of Sweden, Empress Josephine, Napoleon’s wife and even Casanova – used the Aachen and Burtscheid bathing houses for alleviation of their illnesses:

Until today Aachen is a famous and highly frequented health resort, in which 2000 years of bathing tradition are still alive and which has been enriched by the Carolus Thermen opened in the year of 2001.
