There are only two of this type of bunker in the whole Atlantic Wall and they were never used – the war ended before their construction was completed. They are located side by side near Julianadorp – two giants, one of which can be visited inside. Visitors can see the enormous shaft on top of which the gun would have been mounted and through which its ammunition would have been hoisted up. Stelling Den Helder’s willing volunteers will tell you more about the bunkers. The other M219 is used as an observation point for viewing the dunes and beach.
