View of Zell from the Collis Tower

At first glance, the spiral sandstone staircase appears to be enclosed by a gate. However, this only prevents ascent. The descent leads into darkness via the stairs, which are partially slippery due to rubble, followed by a tunnel leading to a loooong, equally slippery staircase that descends into the depths. This tunnel then leads into a long, equally slippery tunnel with loopholes on the sides, at the end of which you return to daylight. Sturdy footwear and sufficient lighting, or good accident insurance, are recommended!

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.

A nice little climbing spot, but it can easily be bypassed by a small path.

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
