The John the Baptist Adit is located next to the administration building of the Dolná Hodruša mining works.
It forms the 2nd level of the Schöpfer mine and is 3,700 m long in total. Precious-metal ores were mined intensively here for at least 300 years, and the very first steam locomotive in the Štiavnica-Hodruša mining district ran underground in this adit.
In the 1960s and 1970s, the 8 lowest levels below the Ján Baptista level were flooded with waste sand from the copper ore processing plant. The entrance portal has recently been restored and is easy to reach. Nearby there are many other important buildings – the miners’ house, the administration building, the Mayer and Mayer II Shafts, the engine house, the crushing plant and the gravity-flotation processing plant.
