As far as I can see, this site was a Flak site covering a band of the countryside from just behind the sand dunes and some inland batteries. The guns 2cm and 3.7cm Flak could also be used as ground defence and for AA cover over a vast area with railway guns and heavy gun batteries under their protection.

Mülheim sitting between the beach and the next level of defences behind. This was one of the strongest defence of the Atlantikwall.

A 1945 photo of the steps up the flak tower. I see there were hand rails running up each side and what look like railway lines running up the steps to draw a gun/searchlight up the emplacement.

It could be a double entry like a Vf2a type bunker.

This looks like an air strike from above and to the right, cannon shell maybe. The bunker looks as though it was here and somebody decided to add a flak position on its roof and as you see. The flak wall is made of different materials and at a different time.

Up on the roof where a gun would have sat. I would say 3.7cm.

I hope the water does not drain into the bunker. You can also see where the cannon shell went through the outer wall.
