In between, the well-known 14 Stations of the Cross are lined up along the Stations of the Cross.

The length of the stations is approx. 700 m with a difference in altitude of approx. 75 m. The historic Way of the Cross is also a small section of the EIFELLEITER premium hiking trail." https://www.eifel.info/a-adenauer-kreuzweg

In the language of the island, the piece of land with the 3 tunnel entrances in the so-called Kupferberg has always been referred to as a "gold hole". However, neither gold nor other precious metals have brought any monetary benefit to the citizens of the island in recent times. Rather, after mining was abandoned in the 1930s, the tunnels served as a place of refuge from bombing raids in World War II.
