This is Sauerland Wn 120a. Two bunkers are lying at a lagoon, which was formed by quarrying after the war. The bunkers have tumbled over and so all floors and walls are leaning. Exploring the bunkers with a flashlight is a test for your sense of balance. The observationbunker is placed on the hill. The cupola is still present, but was covered during our first visit in 2003. This 613 is accessible via the emergency exit and we went back for the cupola.
The 637 and the 600 at a row in 2003.
From the other side, in 2013.
