Although not recently discovered we went to have a look at 2 holes from the WW2 era in Hamstreet. The first hole had about a foot or more of water in it when we arrived but this was quickly pumped out to reveal a small concrete lined and concrete floored chamber about 10ft deep
Access was by foot rings in the sides and the floor would have originally been wooden boarding
The only thing of interest in this hole was some graffiti possibly dating back to it’s early days
The second hole, smaller in diameter produced little of interest after a couple of hours digging and has been abandoned. This is possibly an escape route from a WW2 post but the original entrance has been lost over time.
