The grotto was inaugurated in 1954. Until the end of the 1960s, a procession to the grotto took place every year on May 1st and August 15th. Beautifully designed and inviting place. There is more information about the history on the board on site. Definitely worth a visit!

Beautiful rocky entrance along the way. However, nobody was inside 😁

Iron ore and red iron ore were already being mined in the Eisensegen pit and was the largest pit with reel shafts, blind tunnels, opencast mining and a cable car. This tunnel was only built in 1937. Stone pillars on the Aue testify to bridge pillars of the mine railway.

There has been a Mariengrotte here since 1954. Chaplain Böß had the idea for this in 1953. A procession to the grotto takes place here every year on the Assumption Day. Nice and neat :-)

Simply fascinating and definitely worth a visit to the eternal ice. Pleasant cooling off on hot days and you can also linger here very well. A sign explains the phenomenon of "Eternal Ice" in a way that everyone can understand. We will definitely come back here.
