Millstone Cave (Mühlsteinhöhle)

It is unbelievable under what conditions people mined millstones here in the Middle Ages. The porous volcanic rock is popular because it does not become smooth when it is ground, but remains sharp-edged.

Well accessible cave. It is very good to see how the millstones were worked out. A good headlamp is recommended so that your hands are free to take pictures. I personally found the cell phone camera too dark

The porous stone on the Rother head is ideal as a millstone, as the constant abrasion always opens up new pores that keep the stone sharp. Millstones have been cut from the lava stone here since the 13th century. With simple tools, including swelling wooden wedges, the millstone was carved out of the rock - mostly above the head.
