In the Altlayer Berg, a few hundred meters from the Adolph-Helene mine, an unbarred tunnel leads deep into the mountain, directly on the path by the mountain stream! Don't forget your flashlight, it's 50 to 100 meters!

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 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.

The Altlayer "Schießkeller" 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.

What is the historical significance of the underground sites in the Ober Kostenz region?

The underground sites, mainly slate mines, are historically significant for showcasing the region's long tradition of slate mining. They highlight the arduous manual work involved in extracting slate and their varied uses, such as air-raid shelters during wartime and later for storing explosives. Sites like the Altlay Slate Mine and Hitzelbach Stream and Slate mining illustrate this rich industrial past.

Can you tell me more about "The Altlayer 'Schießkeller'"?

The Altlayer "Schießkeller" is a historical tunnel that began construction as an air-raid shelter during World War II. After the war, it was repurposed for storing explosives, particularly for local companies involved in forest path construction and slate quarrying. It provides a fascinating insight into its varied past uses.

Are the mines and tunnels around Ober Kostenz suitable for beginners or those new to underground exploration?

Many of the historical slate mines and tunnels, such as the Altlay Slate Mine and Hitzelbach Stream, offer accessible paths for exploration. However, some, like the Elzengrab Mine Tunnel and Barbarasegen Slate Mine Tunnel, are described as 'challenging' and may involve squeezing into narrower sections or dealing with rockfalls, making them more suitable for experienced explorers. Always check specific site conditions.

What should I bring when exploring the mines or tunnels?

Given that many of these are historical mines and tunnels, it's advisable to bring a flashlight or headlamp, as lighting inside can be minimal or non-existent. Sturdy footwear is also recommended for uneven terrain. For more challenging tunnels, additional safety gear might be necessary.

Are there any family-friendly options among the caves or mines?

While specific 'family-friendly' designations are not always explicit, sites that are historical and offer well-maintained paths, such as the main sections of the Schieferbergwerk Steeg (as mentioned in region research), could be suitable for families. Always verify current access and safety information for each specific site before visiting with children.

What are the typical geological features found in these slate mines?

The primary geological feature is slate, a fine-grained, foliated metamorphic rock. These mines showcase how slate was extracted, revealing the rock layers and the impact of human engineering on the landscape. You can observe the traces of old mining tools and the structure of the tunnels driven into the mountain.

What is the best time of year to visit the caves and mines around Ober Kostenz?

As these are underground sites, they are generally less affected by surface weather conditions. However, access roads and surrounding hiking trails might be more pleasant during spring, summer, and early autumn. Always check local conditions and opening hours, especially for guided tours, which may have seasonal schedules.

Are there guided tours available for the mines or tunnels?

The region research mentions that the Schieferbergwerk Steeg allows visitors to walk through its tunnels, and some historical sites may offer guided experiences. It's best to check directly with the specific sites or local tourist information for current availability of guided tours.

What other outdoor activities can I combine with a visit to the caves?

The Ober Kostenz region offers various outdoor activities. You can find numerous running trails, road cycling routes, and gravel biking routes nearby. These activities allow you to explore the scenic Hunsrück landscape surrounding the historical mines.

Is parking available near the cave sites?

Parking availability varies by specific site. For popular historical mines or attractions, there are often designated parking areas. For less formal or more remote tunnel entrances, parking might be limited to roadside spots or nearby trailheads. It's advisable to research parking options for the specific location you plan to visit.

Are any of the cave sites accessible for visitors with mobility challenges?

Due to the nature of historical mines and tunnels, which often feature uneven terrain, narrow passages, and steps, many may not be fully accessible for visitors with mobility challenges. It is recommended to contact individual sites directly for detailed accessibility information.
