This Vf bunker of Widerstandsnest 165 “Frundsberg”, at the edge of the cliffs of Pointe du Riden, France, was a forward observation point for nearby Batterie Todt.
The cliffs are subject to erosion and the ground is slowly crumbling away underneath the bunker. The way it is sticking out of the cliff wall nowadays is not the way it was situated, the cliff edge used to be further in front of the bunker like you can see in this picture.
It is only a matter of time before the bunker will eventually slide down to the beach below.
You can visit this bunker of you follow the coastline path between Cran aux œufs and Cran Barbier, Audinghen, France. If you follow the path further you will find more bunkers along the way.
