Historical Background

The village developed through the thermal activity.

In 1841 Karl-Gotthelf Kind began drilling, hoping to find salt. Solicitor Ledure from Mondorf observed that cows drank with preference from a special water rose; he noticed that this water tasted salty.

In 1846, in a depth of 736m (world record at that time), the drill bit broke and no salt was found. Nevertheless in a depth of 460m a spring with mineral water with benefacting effects was found. The thermalism in Mondorf was born. Two more sources were drilled in 1913 (Source Marie-Adelaïde) and in 1979 (source Michel Lucius). Michel Lucius is nowadays the only remaining active source

Springs & Spas

Source Michel Lucius Depth: 750 m Flow rate: 440 litres/minute pH: 6,8 Total mineralisation: 14 555,05 mg/kg water Minerals: chlorides, sulphates, hydrogen carbonates, fluoride, iodine, sodium, calcium, magnesium, potassium, iron, manganese A “mixed sodium and calcium chlorinated” water that contains a high concentration of secondary elements such as magnesium and sulphate, with a pH close to that of the human skin, together with its minerals, plus soothing, decongestive and anti-inflammatory properties, is, thanks to its extensive beneficial effects, the perfect ally for care treatments.

The major therapeutic effects of moving in thermal water heated at 36°C are: – specific strengthening of the muscles whilst relaxing, – improvement of the mobility of the joints and range of motion, – reduction of muscle spasms and contractions, – considerable soothing of pains and inflations, – stimulation of blood circulation In terms of rheumatology and phlebology the large quantity of mineral salts brings about a soothing state that facilitates movements and relaxes the muscles. For digestive and metabolic disorders, the absorption of thermal water with its high calcium and magnesium content stimulates intestinal activity and activates the secretions of the digestive system. The respiratory system benefits essentially from the decongesting and anti-inflammatory effects of sulphur, the main component of sulphate.
