Cromwell,
I had a look at the photo's of St James Church on the Blitz thread. I found them very interesting. I also noted with interest what you had to say about the congregation being trapped in the cellar when the church was bombed.
I mention this because when I was young I used to play in the church graveyard, I never actually saw the curch because the church had been demolished most probably during the war, but they left a structure standing that I now assume to be the entrance to an underground shelter.
Of course the story then was it was the entrance to the crypts, so even after the door got broken none of us kids would venture down the stairs.(too scared of ghosts)
So it has only took fifty odd years to discover that it was only an air raid shelter like many others we had explored at the time.
cheers,
