The brown highway signs read "Secret Nuclear Bunker" and arrow off the country lane, which is the kind of contradiction the English seem to particularly enjoy. Down a wooded track in Essex, past a few discreet warnings about private property, stands an ordinary 1950s bungalow. Tile roof, white walls, a porch light. Nothing about it suggests that behind its front door waits a hundred-yard tunnel descending 125 feet into the earth, into three concrete floors built to outlast nuclear war. For forty years the British government insisted Kelvedon Hatch did not exist. Now it has its own gift shop.

The dormitories are stacked with iron-frame beds, three high, with no real privacy and no real comfort - this was a place to survi...

The bunker was decommissioned and sold back to the Parrish family - the farmers who had owned the land in the 1950s before the government too...

Photo credit Marathon, CC BY-SA 2.0. Standing in the operations room, where civil servants would have tracked nuclear strikes on illuminated maps, you find yourself doing arithmetic the planners did.
