The Karolina Spring produces a ferrous carbonated mineral water which is slightly mineralized and has a high magnesium content. The water bubbles up under the old colonnade beneath the church and was originally called the New Spring. In 1817 it was covered by a dome with 8 corinthian columns and renamed in honour of the then Emperor Franz I's wife, Karolina Augusta.
Used to treat urological complaints and kidney stones as the magnesium in the water prevents their formation.
