Beneath the ancient town of Motovun where the wild meets the gentle lies the river Mirna valley with its picturesque countryside. It is here that we find a unique mineral spring of Saint Stephan. The first written documents of the water's powers and use were found 350 years ago and the results are still the same. Natural healing powers of the water singles out Istarske toplice in comparation to other European spas and places it on the very top.
