Top 9 Caves around Weißenborn/Erzgebirge

The Red Graben was built between 1614 and 1615. Important tunnel entrances leading into the Mulde Valley, such as the Old Deep Prince's Tunnel, were incorporated into it. https://de.wikipedia.org/wiki/Roter_Graben_(Erzgebirge) Its name most likely derives from the phenomenon that iron oxide was once washed out of the mines and settled on the bottom as a fine red sludge.

Thieves' Chamber at the geographical center of Saxony, Tharandt Forest. Info: The robbers Lips Tullian and Johannes Karasek. In this rock... ...there was a cave that was filled in during the 19th century.

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.

Orifice Alter/Tiefer Fürstenstollen Kunstgraben Roter Graben In the valley of the Freiberger Mulde, the mouth of the most important and longest Freiberger adit was attached to the main adit Stehenden. In the valley of the Freiberger Mulde, the mouth of the most important and longest Freiberger adit was attached to the main adit Stehenden. This tunnel, which was bought free by the Saxon sovereign in the late Middle Ages, was later called the Fürstenstolln. The mouth of the old/deep prince's adit has walls that can be dated to the 18th century. The mouth hole itself is part of a dry set wing wall. Above the vertical joints is a basket arch, including a coat of arms stone with the Saxon coat of arms. In the mouth hole there is a large sandstone tablet on the left joint, which marks the area zero for the area profile plan of the Freiberg area that was made in 1850-1852 and added later.

Mouth hole of the main break of the old deep Fürstenstolln "The mouth of the main adit is about 40 m east of the previous one at 321.2 m above sea level. In the unusual structure, the bottom left of the water column comes to light in a segmented arch, while on the right, three steps lead to the actual mouth above it. The high basket arch is again made of gneiss and set off as a pilaster strip.Since the water flowed across the entire width, a platform made of crossbeams was installed inside so that you could drive down the tunnel.The mouth hole was renovated in 2003 because the pit weather was used for cooling of the district hospital in the corridor." - https://de.wikipedia.org/wiki/Alter_Tiefer_F%C3%BCrstenstolln#Mundl%C3%B6cher

Thieves' chamber by Lips Tulian, among others, and the 18th century Karasek.

definitely walk to the tunnel entrance... it's worth it 😉
