Explored with goingunderground.
This is the second time we've been here, access is a little sketchy and involves the roof falling in on your head and being dragged out by your shoulders, the second time it was a bit safer due to having the right kit.
The bunker is a type that was known as a 'Super Zero'. It may be unique. The Super Zero was a key nodal point in the Special Duties VHF network and communicated with other Zero Stations and In-Stations.
Salisbury was a very important VHF radio station for Special Duties between 1941 & 1944. The Super Zero does not appear to have been operational until November 1943. Prior to this the station was located in a hut above ground.
Access is close to the capped entrance. In this area the walls are lined with thin steel sheet with a thin concrete skim, made to look like concrete blocks. Looking behind the sheets you can see the solid chalk this was dug out of. In this area also is a door made from railway sleepers, with two locks. This leads to what we would describe as the accommodation.
There are two lower and two upper beds...
The bunker appears to be well ventilated although we couldn't authoritively find the source. In the case of the accomodation, several of the airways were underneath the beds, and the airflow exited via mesh panels.
Also in this area was a small 'kitchen' area.
No pictures of the door or kitchen area because I just couldn't get far away enough to make it a worthwhile explanatory shot.
This is what we considered to be the communications room...
There were three workstations and plenty of wiring. A heavy duty mains electricity cable entered at this point and disappeared upwards, as did three possible coaxial cables.
Adjacent to this was this room...
Coming off the communications room, behind a door, was a tunnel...
...which went to a junction...
...which went down another tunnel to what looked like a couple of air inlets, or exhausts. However, where these went remains a mystery.
