Maidstone – 1 Group ROC HQ was built in 1959 and opened on the 25th June 1960 on an existing site for 1 Group Royal Observer Corps that had been operational since 1939.
Maidstone was part of the Metropolitan Sector, along with Horsham, Oxford, Colchester and Winchester. Each Group HQ controlled between 20 and 30 ROC Posts and collated data from all of these sites at five minute intervals. The information was then logged and plotted at the HQ where they would produce fallout predictions based on current weather conditions, log the detonation type (burst height) and location/yield before disseminating this information out to other locations such as UKWMO HQ, Regional Government Headquarters and other military sites.
Since closure in 1992 1 Group ROC HQ has been owned by a local Solicitors who until recently used the structure for archive storage.
It is of the same design as all of the ROC Group HQ’s in that its construction is of a semi sunken type, containing a totally sealed environment for ROC staff to operate in during operations. This particular Group HQ is in very good condition with all of the plant, filtration and ventilation systems intact and most likely operational. Recently the HQ has had a new roof fitted in order to try and combat the obvious damp issues the structure has.
Time was extremely limited at this location so the photo’s were very rushed, apologies for any poor shots!! (I’ve already dumped 70+…)
