The limestone mine in Elbingerode, Germany
In this year's summer, we made hiking holidays in the Harz region in Germany. During these holidays we also visited the "Tagebau Elbingerode", an open-cast limestone mine near the old town of Elbingerode.
Here's the story I wrote about this hike: https://www.schmatz.cc/trips/der-tagebau-in-elbingerode/
