In Dungeness is the remains of a minefield. I believe these were mushroom mines (and I have found a few rusty pieces of exploded mine there). The minefield is a belt (around 100-150 metres long) of three lines of craters, running between the fence at the power station approach road, and the remains of the old school house (which is just by what was once the old railway sidings). It's still visible on Google Earth if you squint.
I am struggling to understand why a minefield would only be a finite length 100-150 metres long, when, surely in WW2, to avoid it (assuming one knew where it started and finished), all one would have to do is walk around the sides of it to gain access to the Dungeness military restricted area. Makes little sense to me. There are a few (hard to find but at least I know where they are) craters on the other side of the wooded area from the minefield belt, but, assuming they are also exploded mines, it isn't 'joined up' with the major minefield belt, therefore seems to be equally useless.
Does anybody know what the minefield was supposed to be protecting, and why the minefield wasn't a complete unbroken belt around the entire Dungeness estate?
