Keighley air raid shelter

As for the history on this place, I have not found any. I have been reliably informed that it is a WW2 air raid shelter and that where it is bricked up was a tunnel into the town center.......this is a very feasible story, but we all know when researching, you have to make your own interpretation, and I do think that the tunnel did go further, but I think it more than likely went into what was a mill very close by (which was turned into a pub/night club).
