One of the best explore's I've seen you do this year. Adding photo stills of things you've found is a nice touch as well. The three episodes you uploaded are worth another watch.
Ohhh yess part 3 is here just as i fonished part 2. Im lovin this ! As a Electrician although im not practicing ATM, i would strongly urge people not to mess with any electrical item, which Matt tried to instill throughout the duration of explores !
Amazing how we could build something like this in such a short amount of time, whilst also fighting a war. Bet we would struggle to do the same today in such a short amount of time, and under such circumstances. So many amazing places under London and other areas that are nowadays just left to decay. So glad we have people like Matt to show us around these places.
we would struggle today because everyone working on the project would have English as a second language and would be paid less than minimum wage. "you pay peanuts you get monkeys" etc etc.........imo
@@badlarry172 when I worked on construction recruitment, we found actually that it tended to be the english workers who were the laziest. Immigrant workers tended to be prepared to work overtime.
Matt... I must of seen 95% of you're videos but this one has been by far my favourite.. the passion you bring and knowledge is next level. The underground stuff is definitely my favourite.
I am glad Jordan had calmed in this episode, I do wonder were the exhausts from the big generators came out, those mufflers were huge so they would have been noticeable from test runs unless they were on permanent. Another thing by the lower ground lift motor where Jordan said about lift counter weight and riding them, I lost a close friend like that but this. Was years ago so hopefully the risk of this is now is low as more secure lift service rooms are in place. Hopefully anyway .
Don't throw breakers and switches on active industrial sites, one of these days you might get a very nasty surprise - and arc flashover, a small electrical fireball !
Yes couldn't agree more nothing should be touched especially any electrical item as in main switches and isolators. As you don't know what the previous engineers have done. Yes they should have locked off switches and isolated things woth warning notices but maybe they didn't due to not expecting the wrecking crew to attend AKA JORDAN LOL
Exactly what I thought. Utterly moronic. Could of caused all kinds of problems sealed themselves in so stupid. Next time Andrew leave Paul ogrady and the chavs at home. Totally embarrassed you
WOW, just that, round and round, down and up, and down and up. So much is in great condition. Aside from the screeching, great exploring. Thank you, Matt, and your crew of misfits. Use the lifts, if you can keep Jordan from pushing buttons. LOL
I remember working down there in the late 80’s installing the partitions within the offices. There used to be a guard sitting by the lift where we had to sign in before descending down to the tunnels. It’s fantastic how nothings changed for nearly 35 years
I’ve seen other explorers in here and they opened the watertight bulkhead doors using the hydraulic levers you found on that mezzanine level. This is the biggest deep level tunnel / bunker I’ve seen so far under London but maybe you’re able to get into the ultra deep level tunnels some day. I think you were very close here as those telecom wires had to go somewhere out of the bunker.
Hi Matt, I just finished watching your three videos on the secret London bunkers. This place was totally crazy how they even built this place. l haven't a clue,this could be a brilliant tourist attraction or a museum, most likely one of your best videos l have seen l thoroughly enjoyed watching. I can't believe this place was here and in great condition. Thanks for sharing your videos 👍
Great series. I need to get myself out and get into some abandoned sites. I work nights so there’s not a lot else to do on my rest ‘days’. Thanks for sharing. Really enjoyed it.
Brilliant part 3 @Secret Vault and Jordan was quieter in this bit bless him. I would have freaked the hell out if i had been in that lift when you stopped it, i would have been screaming higher than Jordan lol 😂
Interesting vid. Curious points 1. If it was a bunker surely there would have been cloakrooms 2. Medical/operating theatres 3. Rooms for high level people 4. Access to other sites 5. Storage areas for food etc
Wow that was insane, such a contrast between different areas looking almost new and others in disrepair. I just can’t imagine working down there. With so many involved in building it how the hell did they keep any of it secret?
I think there’s a way in to the old Royal Mail rail tunnels also. Squatted the new Oxford street building years ago tunnels and doors galore. I wonder what happened to the bunker under the old GLC headquarters in Westminster now a hotel ….
Private bowling alley lol 😁 Great find and that's where most Londonderry pay extra for power being on in this place's. Great video as normal, can't wait to see befaces video it will be mad.
At 5:37 you are showing Control Data Corp disk drives. I used to work on Burroughs disk drives in the late 70s early 80s. The fixed disk drives I worked on had a capacity of 220 Mb each and two of these were in each cabinet.
One heck of an explore it is amazing they haven't found a usage for all of that space and equipment. Also, truly amazing after all the flippin of the switches and turning the valves you guys did not have an Army down there with you. Would have loved to see the look on your faces if one major piece of equipment started up.
The bricked up tunnel with the silver foil was the one where the cables went in and out. You can see the holders for the hooks on one side. You also found the hooks in the ground when you opened the floor panel.
Brilliant explore Matt! I love these old hidden bunker exchanges! Shame all the original Sowter selector racks are gone! I’m sure those empty tunnels must have been full of them! Must of been value in all that cable to of pulled it all out! Bet there was 100,000s of miles of it down there! So cool! Hope you get into Manchester! You did Birmingham I think, was a while ago! Keep it up J
Wow I'm a Telephone cable technician by trade so I found this very interesting. I have never seen something this big before. Our headend locations are nothing like this
1:10:14 - that's a Motorola TRBO Digital repeater. There is probably a leaky feeder antenna system throughout the tunnels for contractors, security and any responding emergency services to use. One concern after the King's Cross fire was the inability of people to communicate below ground or to or from below ground. Mobile phones and airwave don't work down there, nor would the LFB's Fireground radio so BT probably installed it at their request.
Amazing discovery, quite a daring way to gain access. Just a thought, what about leaving glow sticks where you go to make it less likely to mistake new tunnels with ones already seen, a lot of them look the same.
I believe it was built as part of the ww2 deep level shelter programme. Finished long after the blitz it was later adopted as a telephone exchange. The GPO didn't build it, they took over it.
@@bigglesace1626 the tunnels were all hand dug and the earth taken away by lorry’s into the countryside, it had a section d notice on it. It linked Birmingham and manchesters nuke proof exchanges amongst others with 542 junction cables , all sadly gone now .
@@1961kickboxer SubBrit have more details and it seems when the GPO took over they did undertake further work to extend the tunnels in connection with their new function. All fascinating stuff. Matt has posted good videos of visits to the Birmingham exchange and other stuff is out there on the Manchester one.
Wow!!!…that’s some place. That map at the end was interesting, this place is well connected to other sites. I wonder what’s beyond that breeze blocked wall? Enjoyed it, thanks 👍
This shows you guys really need to wear N95/N99 masks on your explores-the "Pectel" shower room you walked into is an ASBESTOS decontamination center, for people in protective outfits who remove asbestos to climb wash the asbestos dust off them. PLEASE take care guys! I only know this because I googled a bunch of things I saw in part one and two of your video last night and found "Pectel" specialise in Asbestos removal, often for government buildings. And decontamination for asbestos involves shower rooms, protective full body suits, etc. And matt mentions the modern water pipe-which linked to the shower room! Nasty stuff-and I hated to see you all walk into the rooms obviously used recently, and obviously with lots of asbestos dust in. And minutes after, seeing Matt sniffling after breathing that stuff in? Not good. Mask, mask, mask!
34:33 looks like it might be a guard tour key slot. It records when security goes to different areas and or sets off an alarm saying they haven't been doing their rounds.
What do the top and bottom black triangle and left and right triangle in a circle signs mean? There on a few doors you walk past. Tried searching up. Thanks secretvault
Haven't got chance to watch the video yet but if they're what I'm thinking of from your description they are survey markers to check for movement of the building
@@TheSecretVault just ordered Dr Bradley Garretts book explore everything. I remember him from a Joe Rogan podcast cheers. I will have a search for some of Duncan Campbells books now cheers. I am sure I have emailed him in the past about ROC bunkers and got a reply 👍
Matt 3 absolutely fantastic videos as u watch part 1 you wonder what will you find next and after part 3 makes u wonder has it all been explored to its potential thank you for showing us whats under our feet
Those white stickers, a circle with four black and white alternating 'slices' I'm sure has something to do with bunkers or civil defence. I'm prob wrong cos I'm usually high when I watch things 😂
I'm not entirely sure but I think they to do with some kind of engineering or surveying of structures, but don't hold me to that, I too may be wrong lol 😂
Point 1. If this is what 'they' seem not overly worried about you finding. What's REALLY hidden? Point 2. Why on earth did you take that 'person' (trying desperately to be polite...) with you?!
Aside from Screech , One of the best explores Iv'e seen in quite awhile. Matt knows a little bit about everything, and alot about nothing. Just tell Jordan to STFU
Just to warn you buddy BT have put you under investigation for the sites you are posting especially the Birmingham cable tunnels. Access is never a walk in job especially the way you went about it on the new market street shaft we both know that 😉
Cracking three videos, probably the best explore i have seen in quite a while... matt is truely the godfather of urban exploration

Thank you, Matt, and your crew of misfits. Use the lifts, if you can keep Jordan from pushing buttons. LOL
One day, they’ll be a huge fire underneath London, and the last thing heard before the inferno will be “yipeeeee!”.
I remember working down there in the late 80’s installing the partitions within the offices. There used to be a guard sitting by the lift where we had to sign in before descending down to the tunnels. It’s fantastic how nothings changed for nearly 35 years
Always love seeing the underground engineering, especially these kind of massive structures. 👍
33:51 look at vent shafts on the ceiling, there is more behind that wall!
one of the best if not the very best explores Matt im speechless you bossed it !

These cables also carry a voltage giving the dial tones.
@@BenLuis732 I think all cables carry voltage ;-)
Haha…..very true. Thanks for this explore, true gentleman
I'd bloody love to visit Guardian Bunker in Manchester, think it's quite a difficult one to get in. Think there's an entrance near Dial House
Yep, been there, done that, and set off the four minutes warning sirens in Birmingham, lol
Love the opening of the door onto the street at 121.40 ...its like an end scene from bbc children's programme

Hello. Good to see you again sir.
Absolutely insane explore! Well done guys, this is the stuff other urbexers can only dream of.
Keep up the amazing work 🙂
Interesting vid. Curious points
1. If it was a bunker surely there would have been cloakrooms
2. Medical/operating theatres
3. Rooms for high level people
4. Access to other sites
5. Storage areas for food etc
I think that was the best bunker expolore I have ever seen so far.
Agreed
Be unreal for a rave down in them tunnels
Wow that was insane, such a contrast between different areas looking almost new and others in disrepair. I just can’t imagine working down there. With so many involved in building it how the hell did they keep any of it secret?
Official Secrets Act
@@TheSecretVault Well yes, but with so many even that seems likely to get breached but maybe not. Bloody mad place though.
What a great series matt thanks for showing us you knocked it out of the park again got to be the best urban exploration channel on yt ❤
@@PomFrit99 i hope i dont get fined 1 billion.
I think there’s a way in to the old Royal Mail rail tunnels also. Squatted the new Oxford street building years ago tunnels and doors galore. I wonder what happened to the bunker under the old GLC headquarters in Westminster now a hotel ….
Goldie Lookin' Chain clart
I just tried looking for 'pectel' and all i can find is a court case where BT sued them. BT has another DLT in Manchester too according to the case.
Probably this company - Pectel Group Limited ... A group engaged as building contractors including specialist asbestos removal and allied works.
Oooo can’t wait to watch this later when the toddlers gone to bed!!
Outstanding explore. The place is massive.
Excellent series, the most interesting underground explore so far.
Awesome set of videos, really enjoyed this trilogy.
Very cool video Matt ,what a place very big and intresting
Private bowling alley lol 😁
Great find and that's where most Londonderry pay extra for power being on in this place's.
Great video as normal, can't wait to see befaces video it will be mad.
Loved all three!! Thankyou, what the heck is beface taking 😂😂 gotta love him 😊
Oh hell yes part 3. Its crazy how people just don't move into these locations and run their own stuff off the free power etc.
Love the map at the end! Most have big financial services/scientific research/ tv-media buildings on the land above now!

A quick tour of nearby places reveals: Goldman Sachs, Deloite, The London Law school, snd the Hatton Garden jewellery Quarter. Any coincidence...?

Those black and white patterns on a sign in every area are for laser mapping. Some good maps exist somewhere. 😊
I'd love to know where they moved all the stuff to
indeed
Where was those Bowling pins and Bowling ball which part of the bunker was it was it on lower level or upper level
Wouldn't suprise me if these places get inhabited again in the very near future.
Hey Matt was that a bit of hardfloor tec 👍😎
A 3.5" Floopy Disk is 1.44 Mb (Edit* not Floppy but quite Rigid tbh!)
Why didn't you lift the grates and go down the ladders under floor just outside the lifts to the street access?
