Recently this picture has caused much mirth among the blogs, but as cold war civil defence is one of my hobbies I feel bound to give an explanation. This was one of a chain of 8 top secret nuclear bunkers from which government would operate in the event of a nuclear holocaust round the country. It is now of course a museum.
It is the tip of the iceberg: for the reality was that in the 1980's we were extremely close to nuclear war: some KGB defectors testify that the Kremlin was getting ready for a pre - emptive nuclear strike from the west. Extensive preparations were being made: some of you may remember the Protect and Survive leaflets, advising what to do in the event of nuclear attack. This did not happen, thanks to none other than Our Lady's intercession!
Right around the countryside are ordinary looking raised manholes to what were shelters used for measuring fallout. These grey speakers below that you might have seen in public buildings as well as the sirens in fire stations existed to warn the population of impending doom. I could rabbit on for ever, but here is a website giving more information: www.ringbell.co.uk
