Hi Skipper,

Yes that is close to Rotterdam. In the 70-ties we took the train to the beach and discoverd the bunker complexes. It was very exiting!
I have here at home a lot of spare gasmaskglasses. Hundreds we had found of those.

Bunkers are not my specialty but maybe I can help you. Just ask......

Were you also in Rotterdam for WWII things or just for the fun?
