Děvín - Adit entrance
You are standing at the entrance to the adit, which lies directly below the original gate to the castle. The adit is a remnant of iron ore mining, which took place here mainly in the 17th and 18th centuries, when the castle had long been abandoned. It was through here that the miners accessed the volcanic vein, whose weathered parts they mined for their high iron content. This passage carved in the sandstone served as a supply and auxiliary passage for the removal of material. The adit stops at a volcanic vein after about 12 metres. From this point, tunnels were excavated on both sides and the iron ore was extracted.
Did you know that...?
There are more passages under the castle itself, some of them are connected with the castle well. The intensive excavations under the surface caused the castle walls to become instable, some of which eventually collapsed and took some of the shafts with them.
The virtual trail
The stop is part of the virtual trail that will lead you to places in the Ralsko Geopark that are associated with iron ore mining.
