Altlay Slate Mine and Hitzelbach Stream
Highlight • Cave
Mining has a long tradition in Altlay. In addition to agriculture, it served as a second pillar for earning a living. In addition to the mining of ores such as lead, copper and zinc, mainly slate was mined mainly for the extraction of roofing slate. In most cases this was done in small working groups of two or three families who leased the mining rights for certain areas from the municipality. The work was very arduous because of the modern equipment; as they are used today, were not available. It was entirely manual work, from driving the tunnels into the mountain to mining the slate blocks. The slate blocks were transported out of the tunnels on a narrow rock railway track with carts to be processed into roofing slate in the Spalthütte. In addition to the family businesses, there was a large amount of slate quarrying in the Hahn community. This was operated by the Rathscheck company from Mayen. This mine was shut down around 1952. There is now slate quarrying again in Altlay. The Theis-Böger company from Bundenbach extracts roofing slate from underground mining in the Giaselrech district. Contrary to the manual work in previous years, almost everything is done with modern machines. Source: Text information board

The Altlayer "Schießkeller"
Highlight • Historical Site
Shortly before the end of World War II, work began on driving a tunnel into the mountain at this point. It was supposed to serve the inhabitants of Altlay as a kind of air raid shelter in the event of possible air raids. Because the war ended quickly, it was no longer completed. In 1958, the Reinhard Weber company rebuilt the tunnel so that explosives could be stored in it. At that time, the Weber company was busy building forest paths, which often required blasting due to the rocky material. As you can see on the inscription on the second door, quite a large amount of explosive material could be stored in the tunnel. Up until the mid-1970s, the Weber company was still storing explosives here. After that the tunnel, also known as the “shooting cellar” in Altlayer parlance, was not used for a long time. It was not until 1985 that the Udo and Hermann Fuchs brothers from Altlay stored material for blasting again in the tunnel. At that time, the Fuchs brothers put the Mosella Il slate quarry back into operation in the Hahn district after a period of rest for 35 years. Unfortunately, the productivity was only low, so that on May 30th, 1990 operations were stopped again. Since then, no more explosive material has been stored in the Altlayer shooting cellar.

Elzengrab Mine Tunnel

Stollen mouth
Highlight • Cave
After the low entrance, you come across a rusty ladder after 10 meters and only looking back reveals that the entrance was probably earlier.
Then it gets exciting, because it's a bit slippery on a slope 15 meters further and a good 5 meters down(!). If you are at the bottom, turn left at right angles. This level leads through several excavation rooms, which are wide but not high, a good 70 meters far into a dome that is also low, from which tunnels lead off on both sides. But you can also go straight ahead 60 meters, then you would have to go through knee-deep water for a good 20 meters and then you might have to go further. The tunnel to the right leads 50 meters to a cathedral and then another 50 meters further. The left tunnel ends after about 45 meters.
So you have a lot to do!

Historically interesting, sure, but it's just a "dark hole."

Construction began at the end of World War II and was intended to serve as an air raid shelter. After the war, explosives were stored here. May 30, 2019.

Mining has shaped the village of Altlay and its residents and given the village its name Altlay. In local dialect, a lay is a roofing slate. Anyone who visits the narrow stream valleys around Altlay will not fail to notice striking evidence of mining here and there. Here, at every turn, you come across the remains of what was once a fairly extensive, predominantly small-scale roofing slate mining operation. Slate is still mined in Altlay today.

The tunnel mouth is about 50m from the path of the dream loop (forest path) away above the slope behind the fenced garden plots on a forgotten and overgrown farm road. After the low entrance, you come across a rusty ladder after 10 meters and only looking back reveals that the entrance was probably earlier. Then it gets exciting, because it's a bit slippery on a slope 15 meters further and a good 5 meters down(!). If you are at the bottom, turn left at right angles.

The tunnel leads a long way straight into the mountain to a collapsed mining dome. There you can squeeze into a tunnel that branches off to the left, which leads to another, two-part cathedral, from which several branches lead up and down, but a few rockfalls prevent you from progressing.
