With a contemporary witness into the past: Hans Zapf takes a tour underground in the Peißenberg Mining Museum. The 85-year-old worked in the mine from 1952 to 1971.

He is pleased that the museum tours are still taking place, even though he is now the last person who can still talk about the experiences underground up close and “not just from books” The path there initially involved a kilometer-long journey through the different eras of earth's history. The first 1000 meters had to be overcome in the conveyor cage.
