As already mentioned elsewhere, mining in Ilmenau dates back to the year 1200. In 1216, Count Poppo v. Henneberg was enfeoffed with the Bergregal by Friedrich den II. At that time one had discovered mineralised steep copper slate near Roda and on the Sturmheide. Presumably, individual miners had been enfeoffed, who extracted copper slate and sandstone in accordance with the mining freedom.

Nevertheless, in the past, evil itself is said to have preached to the damned here from a large, solitary, towering rock spur. Today, the term Devil's Pulpit inspires one to play with associations, as do the drawings of agates found here. Their fantastic outlines, coupled with the unusual shape of the secondary rock, evoke images in the viewer that he would not have suspected in a stone. And on the devil's pulpit no longer an evil demon is waiting for the agate collector, but other executive powers threatening with purgatory... a contribution by Klaus Schäfer and others (in german) |
