@ciberado: I don't know. It's one of many other bunkers of world war II in this area.
The lighthouse is Blåvandshuk fyr near the most western landmark of Denmark.
The height of the lighthouse is 40m. The bunker may be 10m? The perspective is teasing the eye.
And there are many bunkers in this area. So, this is my opinion, the 'Tirpitzstilling' is a good representation of the others.
But you are right, this one has a special form. May be it is more interesting, when you get closer. ;-)
