Mauritius Springs

St.Moritz Bad looks back at a long history of the so called Mauritius Springs, which is a natural water source, well known for its purity and health qualities. Back in the year 1535 the doctor and scientist Paracelsus has re-discovered the healing qualities of this natural water, that contains above-average concentrations of minerals such as iron (Fe), calcium (Ca), sodium (Na) and hydro carbonates (HCO). This unique blend of natural ingredients and its sour taste, makes the water, which our guests can experience at a tap in the adjacent Grand Hotel des Bains Kempinski St. Moritz, so special. The Residences and the adjacent hotel are situated right on top of the Mauritius water source, which has supported people in healing and relaxing for more than 3.000 years, since its first discovery in the Bronze Age.
