Beauties of our Homeland: Geyser of Herľany Date of Issue : 19 September 2016
The geyser of Herľany is located in the village of Herľany on the western slopes of the Slanské Hills within the complex of the former Herľany-Rankovce spa. It is an man-made cold geyser which sprang into action after the drilling of a new well that aimed to increase the yield of the mineral springs in the former spa. Unlike hot-water geysers, the temperature of the geyser of Herľany ranges between 14 and 18 °C.
It was declared a national natural monument in 1987. Its uniqueness is also confirmed by its listing in the UNESCO World Heritage List since 2002.
