The Thermal Water
The 18 pools have different temperatures, ranging from pleasantly warm to hot water of up to 40 °C (104°F). The thermal water originates from the St. Stephen's Fountain, which has a temperature of 76 °C (168.8 F). It is rich in minerals such as calcium, magnesium, bicarbonate, sodium, sulfate, fluoride, and boric acid and is therefore primarily used as a complementary therapy for conditions such as rheumatism, arthritis, skin diseases, or respiratory diseases.
