Mount Wise PLYMOUTH Huge Cold War Navy Bunker Finally Visited
HTML-код
- Опубликовано: 20 сен 2020
- Mount Wise is one of the most highly secured Naval command and control facilities for the British Military. A lot of the command of war fighting and Nuclear Submarines including launch of Nuclear Missiles is now handled by underground facilities such as the Corsham Computer Centre which is situated 150ft underground in a spring floor shock mounted super computer centre with its own "Global Security" centre which is situated above ground with its own data centre which rivals the size of GCHQ and some say is a fall back datacentre for GCHQ who paid for it. The Data Centre masquerades as publically owned to avoid scrutiny and freedom of information requests.
Some extra info gleaned from the web
Military use in the 18th & 19th centuries
The house was designed by James Wyatt and built between 1789 and 1793 in Plymouth limestone.[3] It was originally known as Government House and served as the home of the military Governor of Plymouth; it later housed the General Officer Commanding Western District until that army command moved out in 1905.[4] The house was then used as the home of the General Officer Commanding Wessex Area until 1934.[5]
Naval use in the 20th & 21st centuries
The naval Commander-in-Chief, Plymouth, who had previously been based next door at Hamoaze House, moved into the property in 1934 and it was renamed Admiralty House.[6] At the same time Hamoaze House, was handed over to the Major-General commanding the Royal Marines.[6]
Area Command Headquarters and Plymouth Underground Extension
In 1939-41 a partly subterranean complex of buildings was constructed in the grounds of the house, within the ditch of the old fortifications, to serve as a combined RN/RAF headquarters for maritime operations; similar Area Command Headquarters were constructed at the same time close to the Royal Naval Dockyards at Portsmouth, Chatham) and Rosyth.[7] The Prime Minister, Winston Churchill, visited the house and the combined headquarters in 1941.[8] The headquarters were expanded during World War II by a series of tunnels, known as Plymouth Underground Extension (PUE), which formed a sizeable bomb-proof bunker complex under the garden of Admiralty House; it could be accessed from Richmond Walk, Blagdon's boatyard and Hamoaze House as well as from the headquarters building itself. PUE was closed in the 1950s but the headquarters block continued in use.[9]
Post-war
After the war the combined headquarters (renamed Maritime Headquarters) remained in use as headquarters of the Commander-in-Chief, and as such provided command facilities for NATO operations in the Eastern Atlantic, together with local co-ordination of RN, RAF and Civil Defence capabilities, and assorted intelligence and maritime surveillance facilities. In the mid-1980s and early 1990s the facility was comprehensively upgraded.[6]
After 1969, Admiralty House became the home of the Flag Officer, Plymouth until that post was also disbanded in 1996. The complex was then used to house a number of different operations on a temporary basis until 2004 when it was earmarked for disposal.[6]

The gate has been repaired with a new sheet of metal so you can no longer access this way. However, one of the tunnel entrances along the public foot path above Blagdons Boat yard. Has been interfered with. The entrance is covered over with a solid bolted metal grid, inside is another grid (less secure). This has been kicked down from the INSIDE. So someone has been inside the tunnels. It has given a clear view down into one of the tunnels. But you cannot access them.
The inner grid has been down for a few days at least and no one has put it back up yet.
The security you encountered in the previous video are from the Mount Wise Housing development (luxury houses and apartments being built in the newer Admiralty House). The original Admiralty House is now Hoamaze house.
If this place is not secured it will be a grow room by next week😬
Thank you Matt, was waiting to see the inside of this for a while.
25:21 inside the CCA those trays would have contained fullers earth. Fullers Earth is used for absorbing chemical agents which may have contaminated your hands during an air raid or enemy attack. The contaminated fullers Earth would then be collected in trays or bags and then you would proceed to the centre section to change into clean clothing. The CCA is usually between a set of heavy duty gas tight doors which were in,y closed when the bunker went into lockdown. Exercise or real no duff situations. So when the gas tight doors were shut, the only way in and out of the bunker was via the CCA and only one set of airlock doors can be opened and the area between had to then be purged before anyone else came in.
Then going back out to the entrance of the bunker would be the heavy duty blast doors.
Cracking opening/10 haha
The King of URBEX surely and deftly eclipsing the others..
Looks like one hell of an underground complex👍
Another epic adventure!👍✌💛
The problem with all these bunkers. During the 80s and 90s there was a MASSIVE government spend to get all of the UKS defences up to date. This involved so many bunkers like the radar network and all the comms which the RAF were in charge of … but when the wall came down in 91 it threw a massive cat amongst the pigeons and in 95 there was options for change and the military systems all came under revue. Technology was changing fast everything changed and a lot of the big projects were still under development and a lot of projects got scrapped as the tech become obsolete. So a lot of these places went onto care and maintenance.
Always appreciate your videos Matt 😊
Yet again another fantastic video
What an excellent explore. This is one of the best I have seen. Thanks Matt. It is a great video of an amazing achievement.
28:14 those MOD property phones where part of the GPTN general purpose Telephone Network. They were located throughout the bunkers and were maintained by BT at the time. BT had a small bunker PABX system in the bunker. You were probably in one of those rooms earlier on near the Battery UPS equipment. The UPS a system was to keep the power supply to the PBX and other essential systems. But there was also was another telephone system inside the bunker connected to the MOD network of which there were many.
The military system ran on a -51V DC power supply fed from a huge bank of lead acid battery’s which is why you saw rooms with tiled floors. Regs said that all power rooms where batteries were used had to be able to contain leaks so they were like wet rooms if you like. The first aid stations you saw were for treating staff who may have come into contact with acid eye wash stations, alkaline for decontamination during leaks etc.
Dude, you are a legend. Thank you for such brilliant content, and you have a fantastic knowledgeable brain.
Keep up the good work.
Fascinating video, thanks.
Brilliant video guys. Really enjoyed watching this. Very informative too. Amazing what there is about and pretty much right on my doorstep too! Liked and subscribed now.
Love the vids matt I still run in my vids lol cool bunker
ha ha Security 😋. Great drone footage and ephoria music, like it. Wow the bunker is like a time warp for me. I joined up in 1996 and all the tech was like this.
Interesting, thanks!
an awesome explore!
Yet again another amazing video mate keep the gd work up 👊👌
Yeap Seen this one Matt!!!; ) Classic Matt's Security Voice!!! Scared off the idget's
1st class video to watch thank you take care kind regards from me kenneth👈💀💖💖💖👍
Amazing Explore
thank you matt good vid and in joy watch ur vid...............jy
Been in the bunker my self and it’s amazing we went in a different way tho
I would believe the red indicates the ups system (uninterrupted power supply) this keeps the power on until the generator kicks in. This is to stop your Data being interrupted e.g having to reload or start up all your computer's and to keep a safe secure environment. The red and blue arrows indicate the air direction and to indicate it's mixed heat so probably the offices. If you find a pure blue it indicates cold air only for comms room etc
I wonder what places you have worked. very descriptive. lol
Liked the vlog from Margaret P
Please go back and do the tunnels 🤞🙏👏❤️
9:50 And WHEN it drops ........ you Gonna feel it
No I was going to say I thought I've seen this before but still it's a good video
Many of the system X exchanges installed during the 1980s continue in service into the 2020s.
System X was scheduled for replacement with Next Generation softswitch equipment as part of the BT 21st Century Network (21CN) programme. Some other users of System X - in particular Jersey Telecom and Kingston Communications - replaced their circuit-switched System X equipment with Marconi XCD5000 softswitches (which were intended as the NGN replacement for System X) and Access Hub multiservice access nodes. However, the omission of Marconi from BT's 21CN supplier list, the lack of a suitable replacement softswitch to match System X's reliability, and the shift in focus away from telephony to broadband all led to much of the System X estate being maintained. Later software versions allow more concentrators to be connected to the core of the exchange, and thus BT are rationalising[when?] their System X estate by re-parenting concentrators from old exchanges with Mk1 DSS onto newer exchanges with Mk2 DSS, often converting DMSUs into CTLEs (combined trunk & local exchanges). The need for these CTLEs to host large numbers of concentrators (90+) has resulted in unacceptably long restoration times. As such, the exchange software has been heavily re-written to speed up the restoration times. Previously, the exchange would bring resources into service in a fairly random fashion, whereas the new software concentrates on getting service back as fast as possible through reduced downloads, faster downloads, bringing subsystems and concentrators back up single-sided etc. Closing the subsequently redundant Mk1 exchanges enables a saving in floorspace, power and cooling costs, with some buildings given up entirely.
never ceases to amaze me on how old certain tech systems are that keep governments running.
your a free lance journalist brining to the publics attention all your investigative work perhaps get your own lanyard ?
So much stuff is so familiar I could tell you so much about these places….
Same
32:34 the blue electrical filter unit on the wall we still fit those to this day.
commenting one minute in..this is going be good.
38:15 that looks like one of the mess dining rooms. Those tree partitions were used to divide up the eating areas.
Bob Lazar, there's a name I've not heard in a while, probably still trying to decipher Papoose Lake.
19:50 The tiled floor suggests a battery room.
Yup I went to get in a week after seeing the video and as mentioned new sheet of metal
36:54 it must have been the control centre for naval ops. If you are ever in Liverpool visit the Western Approaches operation centre a smaller scale bunker but similar to this,
They probably have build a much nicer one they use now.
Problem is , That Kids geht in and destroy all this should be preserved in my opinion . But your Films are very very nice
Try tellingt the UK Mod... who dont care about anything
Interesting. I wonder which of those rooms was where the radio operators worked. I ask because I had relatives who worked there but, of course, told me nothing as I would expect from one in the services. I hope they do make this more secure to stop the mindless idiots doing any more damage.
It was, I worked there.
1:00:20 What a beauty
Just walked past this morning and they’re removing two transformers from the sub station onto a truck
The big dude looks like shredder from TMNT
49:45 veristron manufacture copper to fibre converters. this is essentially a tempest "break".
cant beleave you are walking around down there without face coverings because u are all on camera lol , and no gloves , anyone like MOD see this or police you are bang to rights , and fuked for being there , but there again anywhere you been is the same ,, crazy , but dam good videos i love watching your vids , i used to watch dans channels BUT now i watch more of yours , seems to be more real in what you do .keep up the good work
That’s a damn shame what those kids did...no respect for anything let alone history
Me and my lot beat you their but its so good @adventure_post_
Awesome vid. I worked in that room at 21:21 in 2001. Had a cracking few months there. What a shame to see it like it is.
Im really glad people who worked there get to see it again before it is changed beyond all recognition.
@@TheSecretVault It was a great place to work with a good mix of people there too. Great bunch of lads that worked at the security office at the front of the building. Oddly, most of the rooms you showed I never went in to. I wonder what the future holds for that place??
Used to work there MTI
Those doors that closed when the fire alarm went off were held with magnets
37:15 that phone number was a GPTN number … Bath would be connected with the Corsham Bunkers / Rudloe Manor etc which amongst many roles was the Network Control Centre for the comms …along with the UFOs that everyone think was done there hahah
You should look up history hunter ww2 it's really good it makes you think
A place like this would be good for a base if civil war breaks out!
System X was developed by the Post Office (later to become British Telecom), GEC, Plessey, and Standard Telephones and Cables (STC), and was first shown in public in 1979 at the Telecom 79 exhibition in Geneva, Switzerland.[1] In 1982, STC withdrew from System X and, in 1988, the telecommunications divisions of GEC and Plessey merged to form GPT, with Plessey subsequently being bought out by GEC and Siemens. In the late 1990s, GEC acquired Siemens' 40% stake in GPT and, in 1999, the parent company of GPT, GEC, renamed itself Marconi.
When Marconi was sold to Ericsson in January 2006, Telent plc retained System X and continues to support and develop it as part of its UK services business.
Rember the system x being show cased on the bbc tommrows world
All the communication gear and electronics would be screened against EMP after a nuclear blast, hence the Faraday cage conection around the blast door.
39:55 red usually means either fire systems or secure comms
Shame to se the damage done by the ferrals great explore though indeed hope you made those phone calls
I would add, the small door could be the old service tunnels which are the old ww2 deep tunnels but they are dodgy as
Yeah the red painted routes is called an approved route where the DII(S) would be connected to ie the red network
Guys Red is UPS backup AC
Secure Earth is the ground grid hooked to the in house ground grids
early 2000s I was last there, before the MOD sold it and it was fully commissioned ;)
any interesting or cool stories you can share about your experiences there? like funny events or daily happenings. its always great to hear from the people who actually experienced these places. similar to learning history.
Depressurising extinguishers and accidently killing the Commodores flower bed with an AFFF extinguisher.@@geronimo5537
I had 2 drafts to CC Mountwise. Good number, and good times with the watch on some savage runs ashore
FFO plymouth.........Flag officer Plymouth
48:34 is probably cable tunnels
So don't check to see if the fire hose in running?
gets into base.... power is on... turns on security cameras to make sure security isn't coming.... :p
So I would love to know what you think a chav is
Those Cap banks are used to filter brownouts
Touching the beryllium leaf springs on the EPM door not good for your health lol
Ha! I worked here!
You can get a tour IF you ask!
who do you ask?
Hello Matt how are you EVER going to top this?
Watch in the next week. Something crazy and big is coming.
55:27 - why the police tape?
Hasn't this already uploaded
As You might have spotted since posting this comment, it's a version 2
@Scotty Bee I'm unsure, as I did not see the V1 upload sorry
@Scotty Bee I only watched the first couple of minutes ( saw v1) there's an explanation on this one about the method of entry and why it was secured as it is
Love these ones of the bunkers,i really hate the twats who get in these places and destroy.
Could i ask why you had to climb up a bank to gain access rather than go through the gates?
You walked into and padt my old offices when I was Guzz based.
Bet you were a nightmare kid, touching everything without a clue of what it does 😊
Shame sime of the racks were not still there and live, they could hive a nasty bite.
Bolt and nuts 🤣 yeah, right. Break in and entry for Police.. No matter what you say to them.. You should start the videos after "someone" has allready smashed the locks, thats video evidences for polices right there 🤦♂️. Also, how stupid it is to touch all those fuces, while you dont know what they do, there could be someone working with electricity, and you turn than on, or there could be some door that wont no more open and someone is now stuck cause you clicked it off, or there could be massive water damage, cause you turned off that sump pump...
Good that you closed the door from the Childs. "im under 16, you cant blame me"
What a great place to explore. It a shame that punk kids would come in to trash it just for sh!ts and giggles. They have no respect ruining things for others. T.A.C.
Noddy guide that’s standard military speak for a user guide hahah…
Need Renovating Chinese are Coming
How do you find places like this before the vandals wreck them come on tell me
Spoiler alert!!! Didn't get busted
Unlucky me and the boys beat u to it
@arrran._
Insta if you wanna get in there a different way
And what do you know. The Military are using a FLAT scale rule for the longitude and latitude . Kind of pus the flat Earthers on the map! Well you learn something all the time.
measuring with a curved ruler is more effort than its worth
Man, the guy talks a lot, but he has no idea. He has to keep repeating himself, the braggart!
