There isn’t too much that can be said about this post as you can see from the pictures. I’m not entirely sure when it was capped with concrete and steel bar but its at least 15 years ago, also I’m not sure if it is just a cap or in fact they poured rubble down the shaft and topped it with concrete. If I run out of things to do before I die I might go back with a large can of PlusGas and ‘FSM Cam’ it just out of idle curiosity.
Great location geographically with great vision all round, or certainly would have been before the odd building and trees that have sprang up since the 1950’s. Bedford is one of those unusual counties with very few ROC Posts, despite the fact that Bedford ROC Group HQ No 7 was the HQ for the UKWMO Midlands Sector, covering many more counties at the time.
Nature has certainly claimed back this post…

This visit was more of a recon than a full visit and as such was done on my way home from work with none of my gear and wearing only a t-shirt. As you can see from the pix this entire site has been consumed by nature, something I kind of like to see which is why I photographed it as is, instead of coming back tooled up. The t-shirt was an epic fail as the stingers here are 8ft high and the brambles twice that, in fact this compound is so densely overgrown you could walk round it without even knowing there was anything in there….I never did see the air vent, I would have been stung to death trying to find it. Water levels are the lowest here for a very long while with approx 10ft of the shaft visible (it’s been up near the top before). I also had to extract fast as I heard voices coming towards me from the other side of the hedge so apologies for the crap pix….no tripod, falling down rat holes and legging it didn’t make good photos.

It’s been a ROC Post Fest this last few days across several counties, I’ve hit up 8 posts in 6 days and the 9th planned for tonight but this one wins the FUBAR award so far, not only has it been stripped bare inside, its now Fly Tipping Central with the shaft totally full of refuse/junk/detritus
I was on my own and also short on time so I didn’t attempt to start removing the trash, plus I wasn’t sure of the contents of the black bin bags
The compound itself is chest high in stinging nettles so I’m not sure what original items might be laying around, I suspect none though.
Originally there were some 200 observation posts throughout the country and their role was to provide visual detection, identification, tracking and reporting of aircraft over Great Britain during the World Wars. Early Observation Posts were often crude and un-fortified but during the war many were rebuilt from brick and had sandbag defences.
On 12 May 1945 when the German Luftwaffe had ceased combat operations the ROC stood down, however it wasn’t long before the threat of Cold War arose and the ROC were reinstated.
In 1957, the United Kingdom Warning and Monitoring Organisation (UKWMO) was established under Home Office control to provide essential information about impending nuclear attacks to both civilian and military authorities.So that the ROC could work with the new type of threat the old monitoring posts were replaced with something that had protection from nuclear blasts.
Between 1958 and 1968 a countrywide building programme resulted in a network of 1,563 underground monitoring posts, approximately eight miles apart, distributed throughout England, Scotland, Wales and Northern Ireland, at an estimated cost of almost £5,000 each.The bunkers were built by digging a 25 feet deep hole, placing a reinforced concrete bunker in the hole and then burying it under compacted soil.A single hatch to the surface was the only entrance/exit with a 20 ft vertical ladder that lead to an underground chamber 7ft x 16ft x 7ft high.Posts were typically grouped together in threes or sometimes four, to form a cluster. One post in each cluster was a master post and could communicate directly back to ROC Control using a Tele-Talk device connected to ROC Group HQ and the Carrier Warning Receiver.
No telephones were provided. Each ROC Post was manned by 2 to 3 people who ate and slept in very primitive conditions as there was no electricity or running water in the bunkers, toilet facilities were by way of an Elsan Chemical Toilet located at one end of the bunker.
The ROC Post had a variety of external equipment fitted as standard:Bomb Power Indicator (BPI) – This would register the pressure wave from a nuclear explosion passing over it and the results were read on a dial inside the ROC Post.
Ground Zero Indicator (GZI)– Basically a crude pinhole camera that could ‘photograph’ the fireball of a nuclear explosion.Radiac Meter – Used to count radioactive particles
Fixed Survey Meter (FSM)– Replaced the Radiac Meters and used to detect nuclear fallout. (The FSM could be safely operated without leaving the bunker)Cross section of a ROC Post
After bomb a detonation, the direction, elevation and spot size of the fireball and reading of the pressure wave on the BPI would be passed to ROC Group HQ using the Tele-Talk unit or Radio. Group HQ would use the direction information from two or more posts to determine the exact point of detonation by using triangulation.
The end of the cold war and advances in technology eventually brought the end of the ROC and the monitoring post and group control personnel were stood down on 30 September 1991.
Amazingly hundreds and hundreds of these ROC Posts still exist (although some have been demolished) and even more amazing is that many still have the original equipment and supplies intact inside, it seems many ROC volunteers just climbed up the hatch and left everything where it was. Sadly there are also many existing ROC Posts that have been burnt out or heavily vandalised by kids.
A brighter end to this story is the emergence of ROC posts being restored for posterity, perhaps the most famous of these is 23 Post Skelmorlie in Ayrshire, Scotland. 23 Post has been totally restored and is open as a museum on certain days in the year
This is Sutton Bassett Post 11, part of the Bedford 10 Cluster.
10 Post (Cold Overton) was the Master Post with Sutton Bassett 11 and Clipston 12 making up the cluster.
