In our region, the healing properties of water were first used by the Romans, who especially appreciated hot sulphuric water, as well as other hot springs. For the nobility, as well as ill and wounded soldiers, impressive buildings with therapeutic facilities were built – swimming pools and hot tubs decorated with beautiful mosaics and fountains. The fact that the Romans used thermal waters throughout the year, laying floor pipes for hot, heating water shows how the cult of using thermal waters was highly developed at the time.
