higher - this tunnel was the entrance mining work to the copper ore deposit of Červený vrch. The mining work was excavated by hand with a number of other mining corridors, following the mineralization in which ore was mined. In this mining work you can see the system of ore mining, whether in small chambers or. sinkholes and chimneys. Interesting and precise handwork can be seen in the foundation of the extracted spaces.
lower - is at a distance of about 150 m from the upper tunnel to the north. Like the upper one, this one was excavated as an entrance mining work to the ore reserves of Rothenberg Hill and also torn apart. Both in the tunnel and in the entire mining work, there are a number of side trenches, mines, chimneys and decently excavated works for the purpose of mining copper ores.
