Fascinated to hear Peter Hennessy talking on the Today programme about the publication of the War Book - the step by step guide on how the government would handle the countdown and initiation of nuclear war.
As part of that plan senior government officials would speed by train from Paddington to Burlington. You won't find Burlington on the map; it's actually a gigantic underground bunker beneath Corsham.
We used to joke about this when I worked at The Bath Chronicle because it was fairly common knowledge. So if we knew, undoubtedly there was a missile sitting somewhere in an icy Russian silo with Corsham tapped into its targeting system.
I wonder if it is still there?
Some years ago me and a colleague did the local rite of passages which is to try and get in to the network of caves and bunkers through one of the many holes that dot the hills.
First stop is a pint at The Quarryman's Arms where you can get a map and a very decent 6X (the pub is actually chained to the hillside trivia fans).
Then is was a hike to find a good-sized rabbit hole and down we went. In six hours of flailing around we came across old mining equipment, a cavern called the Cathedral and not a lot else. When I watched The Descent it brought back memories; without the crazy monsters.
Some have much better luck (or better maps).
And if you want to see the War Book then you'll have to make an appointment to view it at the National Archives.
