Top 20 Caves ビューヒェンベウーレンでの

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.

Again and again you come across evidence of slate mining

I didn't try to go in.

Cave in a huge rock, where slate was also mined. The cave, which leads slightly downwards, is filled with leaves that are sometimes waist-high at the entrance, so you have to feel your way carefully with your feet because there are large rocks, deep holes and slippery slate slabs under the leaves.

Small cave that you can tread carefully (clammy, slippery, there is sometimes water in it). The illumination with the mobile phone is completely sufficient, the light yield for a mobile phone photo without a flash was even sufficient.

Small cave, don't forget a flashlight!
