Norfolk Pill-Boxes

[Gil Boyd]

I know I have mentioned it before on here, but of course these reminders of WW2 are in view..............I wonder how many "bunkers" that are still full of arms to provide covert operations had we been invaded are still out there unfound.
As I understand it, only a few were trained and in the know of their location..........one has to assume there is a centrally held map somewhere with them all logged. I watched a programme the other night where one was shown with its entry through a false panelled brick wall.
