My mate Sam and I realised that we didn't know very much about the series of bunkers and posts littered around the UK, built during the Cold War and now abandoned. This bothered us greatly so we set out to educate ourselves by venturing underground at various locations.

A tiny observation post, one of thousands, first used to spot enemy aircraft on bombing raids during WW2 and then used to house equipment with which to measure the impact of a nuclear strike. By chance I also stumble across a hidden trove of treasure which is part of a worldwide movement called GeoCaching. kEwL!!!

NOTE: The bunkers were used to measure the power of a blast using the BPI (Bomb Power Indicator) and not the fallout levels as we originally thought. Presumably with thousands of ROC bunkers recording how powerful any blasts were and sending the data to a central command it would be possible to draw up a map of where any strikes had been and then estimate the damage that had been caused.

I found the GeoCache box by chance. It turns out it's a large treasure hunting game spread throughout the world!

Another Obersvation Post is closed with super-heavy-duty locks. Fortunately the next one we check out has only a car tire blocking our way. It also had a bizarre little watch tower which, at 2 meters high, didn't seem to be much use seeing as how OPs were for looking out for enemy bombers and mushroom clouds.

NOTE: The appliance which Sam originally thought was a shower was in fact a water pump used to drain the bunker if it got wet. The only sanitary facilities that a worker in the bunker would have is the chemical toilet.

Not content with the tiny little Observation Posts we'd found so far Sam and I ventured off to a large abandoned underground nuclear complex which we read has been used by satanic cults in the past.

With its delapidated floors, rusty spikes, pipes and chains and with hardcore devil porn decorating most of the walls this bunker is an ideal location for a family picnic.

NOTE: Apparently, in the 1970's the Military Police were called to remove a cult of witches who had moved into the abandoned bunkers and who are responsible for all the delightful graffiti that covers the place.
