(4K VIDEO ) SECRET WW2 bunker found in Suffolk part one

hiking in suffolk and found a ww2 bunker that was overgrown and forgoten about. I had no torch to explore . no way i am going in there without a torch
have seen many creepy videos. found some Tank traps . lots of old buildings with thick walls shutters. and a strange area that I can't work out its purpose. don,t think there was An airfield in Trimmly st martin not 100% sure on that but ? what i have learnt from my search on the internet. It was a gun in placement that was meant to fire appone the docs if the germans landed. give them something to think about the location. The tank traps and the bunker makes sense now . will be going to the hook of holland soon as they have guns there as well.
