The “Lange Wand” (long wall)

The “Lange Wand” is like a window into Earth’s history: from the Ilfeld porphyry (280 million years) to the copper shale and the Zechstein limestone (250 million years). In the mine of the same name, copper shale has been mined since the 16th century. Here, in addition to cobalt ore and barite, you can also admire fish fossils, the so-called “copper shale herring”. … Continue readingThe “Lange Wand” (long wall)

The “Schneckenstein”

The Schneckenstein is a well-known topaz rich outcrop located in the identically named district of the town of Muldenhammer in Saxony. The outcrop rises 23 metres above the ground in a mostly flat surrounding. With a height of 883 metres above mean sea level, the Schneckenstein is one of the highest points in the Upper Vogtland area. For protection purposes, the rock itself and its surroundings are fenced and can be visited during opening hours. On the 5th November 1938, the Schneckenstein was named a natural monument and added to the Saxon geosite list as number 259. The Schneckenstein is part of a joint geological research project of Topaswelt Schneckenstein, TU Bergakademie Freiberg and the Vogtland Geoumweltpark. … Continue readingThe “Schneckenstein”

The “Familienschacht”

Beneath the town of Freiberg in Saxony exists a large underground mining system dating back to the 18th century. During construction work at the Untermarkt in 2018, the so-called family mineshaft (German: “Familienschacht”), which was used to mine silver, was rediscovered. Due to the visit of Alexander von Humboldt, the Familienschacht is also known as the Humboldt Shaft. For safety reasons, the mining system is not accessible to the public. However, a 3D model was created to enable visitors to experience it. … Continue readingThe “Familienschacht”

The Externsteine

The Externsteine are a group of spectacular sandstone rocks located within the Teutoburg Forest. The rocks were formed from sediment that accumulated within a marine basin many millions of years ago, which after burial and lithification were tectonically uplifted and tilted. People have visited the rocks for many hundreds of years and they are regarded as a place of worship. Humans have now changed the appearance of the rocks by building bridges and stairs. There are also artificial caves and carvings. … Continue readingThe Externsteine
