Wow, thanks for posting these.
I love seeing these secret and derelict places, I don't know what it is about it, perhaps a mixture of appreciation for ingenuity, wonder at what
must exist now, and happiness that such places have never really been used for purpose.
It's remarkable how much we waste, after so much effort and time has gone into these places. They should be opened up and renovated, sold out to
private buyers, or otherwise utilised in some way.
I'd buy a bunker!
