7. Shaft 1
The mining shaft 1, the so-called “Lingeleloch” 1, was explored by the Institute for Pre- and Early History of Freiburg in 1991. In total, this shaft has a depth of 48 m. On the surface, it has a mouth with the size of 4 x 4 m. With increasing depth, the shaft narrows to 1.5 x 2 m. On the walls, you can see clear trails resulting from the sinking of the hammer and chisel. In regular intervals, you can see cavities on the opposite walls proving that there was a former wooden construction for the securing of the shaft. In a depth of 16 m, a gallery with a height of 90 cm and a width of 45 cm, forks northwest and ends in a collapsed mouth on the slope.
At the bottom of the shaft there is a chamber-like construction from where different routes start leading to the different extraction sites (galleries without entrance/mouth). However, these extraction sites have partially collapsed. Considering these remnants of the underground mining (in a depth of 48 m), you can say that silver ores were extracted with hammer and chisel as well as by “fire planting”.
