Less than 2 km northeast of one of the youngest volcanoes Czech Železná hůrka, a quadratic wooden gazebo Kyselecký Hamr is found. Heavily carbonated spring is bubbling up from crystalline Saxothuringian rocks, but it already belongs to a group of carbonic waters of Mariánské Lázně (Marienbad). It is a typical fractured spring hidden under the layer of sediments (the alluvia) forming the floodplain of Stebnický stream. Mineral water is captured from the sump of smoothed granite blocks, where the year 1698 is visible. Stone collecting for mineral springs is not usual in the region. In most cases springs had wood paneling or hollow tree trunks pipes were used.
Mineral water was reportedly already known in the 16th century, when it was used by spa guests, who stayed in Mýtina and the Bavarian Neualbenreuth. During the totalitarian regime the spring was in the border zone and unavailable for tourists. After the fall of the iron curtain there have been attempts to its commercial use - collecting wells were drilled on the edge of Mýtina and building of a bottling factory was started. The intention, however, has failed and the spring is still accessible.
