Mouth of the Michaelis tunnel in the Mortelgrund near Sayda in the Ore Mountains valley. The mine was built on a vein bearing copper and silver and produced a certain yield, especially in the 17th and 18th centuries.

The arched mouth hole of the Neuer Segen Gottes Stolln with lining wall and quarrying made of quarry stone has the inscription "Mouth hole ... Neuer Segen Gottes Stolln 1817" on the keystone. A small drainage rose branches off underground from the tunnel and emerges not far from the mouth hole in a narrow, brick drainage ditch that flows into the Striegis. The New Blessing of God tunnel, also referred to as Seven Planets Erbstolln as an addition to the Seven Planets Fundgrube, was probably started as early as the 16th century, but only gained greater importance as a water-dissolving tunnel after it was taken over by the Himmelsfürst Fundgrube. From 1817, the treasure trove extended the tunnel further into its pit, so that it not only solved the pit of the Seven Planets Treasure Trove, but also other important shafts in Linda and Himmelsfürst, such as the Siegismund shaft (preserved heap part of the "Brander Revier”, cf. 09208116), the Albert Schacht (cf. 09208666), the Franken Schacht in 1840 (cf. 09208602) and the Glück auf Schacht (cf. 08991313). Previously, the Himmelsfürster pit was drained from the Thelersberger Stolln (cf. 09208657), which is about 21 meters higher, but the pit water was then able to drain away at a greater depth and over a much shorter distance via the Neuer Segen Gottes Stolln. Including its tunnel wing, the tunnel has a comparatively short length of approx. 6.6 kilometers. From 1854 onwards, Himmelsfürst was able to drain into the Moritz tunnels, which were even lower, so that the Neuer Segen Gottes tunnels became less important in the years that followed. From 1947 to 1950 it was made usable again by SAG Wismut and again discharged pit water from the western part of the Himmelsfürst pit and from the Glück auf shaft emergency drainage system. The adit also served as flood protection and relieved the Rothschönberger adit. As an important water release tunnel for the pits in Linda and Himmelsfürst, the Neuer Segen Gottes tunnel is of local and, above all, mining-historical significance. Its mouth, together with the water drainage ditch, are surface testimonies of this drainage system, which is so important for mining at greater depths and are therefore of great documentary value – also seen in connection with the Thelersberger Stolln.

A bit hidden along the way but in good condition from the outside.

A mouth hole of many in the Ore Mountains.

The tunnel mouth hole of the New Blessing God Stolln was secured around 1992 by a mountain security company with steel construction in the area of the quarry stone masonry and the mouth hole itself was protected with a concrete dam that reached almost to the top of the tunnel.

Andreas Alnpeckscher or Weißtaubner Stolln: A tunnel - in the Saxon region mainly written in proper names and traditionally also Stolln - is an underground passage driven horizontally or slightly rising into a mountain or hill from the surface of the earth, which creates a connection to a pit . The main function consisted in the removal of accumulating groundwater and in order to supply fresh air into the mine. Most of the tunnel mouth holes can therefore be found in the immediate vicinity of rivers or streams. The mouth hole of the Alnpeckschen tunnel was set up near the bank of the Mulden and is on the other side of the fence on the premises of the explosives factory. The escaping tunnel water is still used today. The tunnel had drifted east into the mountains. Its course can still be followed safely at the numerous break-ins and heaps.

Part of the Freiberg dynamite hiking route. A great hike for those interested in mining
