I just found you so I am behind. I want to thank you for sharing your knowledge of the equipment you find. I find it fascinating learning about all of this old equipment. Seeing these hidden places is so much fun.
That would probably explain why they had a very high voltage transformer in one of those units? The HV AC would have been rectified to HV DC and filtered to get a high quality DC source for some electro conductive gas used in coating the lens? Note the variac to vary the amount of HV one would need. R we onto something here:)
Yes, I was thinking the same. The element plug pointed out is for the diffusion pump heater high vacuum. And a large vacuum bell would have fitted over the top.
30:00 That is not a lathe or winding machine, that is likely a vacuum deposition machine - to vaporize metal under high vacuum and create a thin film of metal on an object - you can create optical mirrors, filters, etc. The huge column in the middle of the machine is an oil diffusion pump (creates high vacuum by boiling oil inside).
Great place my first thoughts where the tunnels are a hell of a lot older than WW2 they may of used them during the war but they will of made use of the tunnels that were already there. I do not know the area but i wonder if at some time in the past could a building once of stood above these tunnels🤔. If there was an asylum close to these tunnels i would think there are more sealed off underground spaced. It may be worth while looking on google earth for any unusual lumps or bumps in the surrounding fields also crop marks can often by clues. The paraffin heater, lawn mower and vacuum cleaner/hoover i remember very well from my childhood in the early 70s, the paraffin heater was all we had to heat the whole upper floor of the house and it was my job to trek to the garage about half a mile away to get the paraffin. Great video!
I understand 5 of these bunkers were built, this one was later used a s a car workshop. The Optics was another one as @stevewalsh1987 say, that is still in use, and the one matt refers to as being demolished for housing was only partially built due to poor soil. You can find out more with some investigation on sub brit. But as always, a good video matt.
31:00 Since there are high voltage recifiers in there and "vaccum" was mentioned sputtering was one of the things these made. There was a dome on top of that carussel thing and several steps could be done in vacuum. Like finishing steps for valve production.
The black painted areas are where the telescope mirrors would be examined, flat/Matt Black paint to reduce any reflected or refracted light whatsoever when examining the mirror for warpage or distortion.
Hi Matt,you wouldn't think these places existed,very interesting video so meny bits and pieces all over the place,should open the public great tourist attractions thanks for sharing great video
I went down this 2003/4 gulf war panic for bunkers if bombs went off their used to be a air shaft also. used to be bigger when they built the new road you lost the entrance used to be a place for motorcycles and bike repair on entrance when you walk round you sort off go round if the entrance is now gone you might not be able to walk hallway round
Close Matt but no cigar. At 15.40 it part of a turret lathe (See ward turret lathe.) At 16.20 no its not a motor part is the bed and headstock of the lathe. The flat pulleys are for a belt drive giving 3 different speeds. At 17.14 they are the 2 pedistools it sits on. That was interesting Matt. good job.
The two large concave discs would be fitted to the top of the machines the mirror was placed on top of the disc then it would spin to allow the tool on the metal pole to grind and polish the mirror
When I'm out driving here in the states, I often wonder if open fields or wooded area's that have been there for years, not developed or anything if they have tunnels or secret bunkers hidden underneath.
In much of the Midwest and Colorado area those giant fields may have missile bases you'd hardly notice. Explored a abandoned titan missile base east of Denver, looks like a plain empty field. Huge bunker and 3 missile silos below. It's wild.
These tunnels used to lead directly to the asylum. There used to be equipment from Cane hill in there many, many years ago, old wheel chairs and really old gurneys
Drove past here last night, Sat 24th April '21. There was a police van parked up on the pavement and two policemen hunting around the entrance. It may be watched or alarmed now, so be careful.
When there is black carbon deposit around the fuse holders it is because the fuses have blown/melted due to over current demand or short circuit on a number of occasions not because some one set fire to the fuse holders.
I live just down the road from this place and never knew about the bunker. My dad was a patient at Cane Hill for many years in the early 80s. I remember him telling me and my brother a few stories about the many times he tried to escape the hospital and how they found a building somewhere in the woods on the grounds. I remember him saying they hid there one night and got drunk before being caught in the morning and returned back to the Hospital. Maybe he found the bunker and the supply room. Ill never know for sure as he passed many years ago. I dont think its a hospital anymore i believe they transformed it into a private housing estate.
great video Matt have not seen a 15volt battery since the early 60.s .My I ask that during a very quiet time you do some research on your posted video's and produce a History in time revisited but keep safe and Keep posting
31:11 AEG E2800C1000.. These are selenium rectifiers. 2800V and 1000mA I think. The naming was the same for some TVs but they were named like E250C85 for 250V and 85mA
At 47:30, that room is the emergency generator room. The bore to the surface would've been for fresh air in and exhaust pipe out, the concrete plinth for the generator is still evident. Generally placed in a seperate section at the far end of a corridor.
Great explore the brickwork is in really good condition it's a real shame that they seal all these places up they should be kept for historical reasons in nothing else. The old machine looks like a coil winding machine of some sort. Thanks for sharing guys and stay safe.
Hey Matt, it seems the link I posted to a RUclips video from 1960's showing the actual site when it was used for mirror manufacturing was removed by RUclips.
Is that field where the old asylum used to be and if not is the old asylum building still standing elsewhere?. Would those tunnels have once led to where the old asylum was? Cool place. Once again Matt you don't disappoint your viewers x
There's a place more or less opposite the Kenley Hotel on Godstone rd,about 10 mins drive from here,that is still in use as a lense making place.I had to work in it many years back when i was a BT engineer.It's almost identical.I believe they used to make bomb sight lenses there during the war because it's sunk deep into the chalk cliff under Riddlesdown so there's no vibration
Fuel would not be in the other section, there would've been a day run tank on the opposite wall from the generator. There could also have been a fill pipe running down the shaft with isolation valves top and bottom.
nice one matthew nice find any deal what year was made ? in joy watch as all your finds good thank u sir lord matthew will nite you as new king of uk ha of best youtube vids
I'm willing to bet that room you thought was a generator room was in fact where the main ventilation fan sat and the pipe in the field was probably the exhaust vent, or possibly the intake vent.
There is tubes Was electric heaters there’s all over the army Camp when I was a young boy and I reckon those two big machines you was looking at was for making licorice allsorts just a thought all the best
Just came from watching your Heathrow training centre part IIII Interesting explore this looks Matt’s hitting the capital Nice seeing you back in a bunker Matt Wobbly fence lol hehe 😂 Yeah I agree glad they put the pipe there 1:17:45 😂
7:41 - I knew a lot of the old Coulsdon mods back in the day so prob drunk with or fought with whoever put up the mods graffiti lol One chap I was locked up with in Redhill was a proper heavy bank blagger from other side of Coulsdon who was an unrepentant mod and me being a bonehead we often had a "to do" as we were the oldest of the lads spending a long holiday courtesy of being juvenile delinquents.
Exactly what I was thinking. He's standing on the main road between Coulsdon and Redhill, points at the traffic and says "Croydon"! Coulsdon's a really nice area with beautiful downs and wooded areas, I would have thought that those people would make more of an effort to get their facts right.
Matt those holes in the roof made of wood perhaps it was access to get machinery in like the big ass tractor and any outher big machinery and another thing why all the French machinery
I used to go down there 30 years ago, the chimney comes out in some bushes in a field.Once a couple of us went out to the field while our mates waited under the chimney and tried shouting to each other, you could hear it very faintly!
Thank you for sharing. I had the opportunity to witness a rocket launch in 2018. Memorable experience. I uploaded a pretty cool video of the journey to my channel.
I went here when the concrete was new and I can't believe it's open again! Well done to whoever opened it up again!
Is is safe,l I wanna go but I’m scared of asbestos
I just found you so I am behind. I want to thank you for sharing your knowledge of the equipment you find. I find it fascinating learning about all of this old equipment. Seeing these hidden places is so much fun.
Pretty sure the two mystery machines are vacuum deposition machines for applying coatings to lenses. They should have bell jars on them.
That would probably explain why they had a very high voltage transformer in one of those units? The HV AC would have been rectified to HV DC and filtered to get a high quality DC source for some electro conductive gas used in coating the lens? Note the variac to vary the amount of HV one would need. R we onto something here:)
Yes, I was thinking the same. The element plug pointed out is for the diffusion pump heater high vacuum.
And a large vacuum bell would have fitted over the top.
I find it amazing what's under are feet and most of the time we don't even know it great video👍👍
Iks need to go here thanks Matt if they haven’t been here. And that machine looked like a glass polishing machine
Lol that bit at the end when your doing the drone footage 😆🤣😆
this place is crazy how many places are dotted around like this ....great video Matt very interesting
The metal discs are for polishing telescope mirrors they are concave shaped to allow the mirrors to be focused to a center point
Matt, Glen, Beno, Jordan = The Urban A-team. Awesome vid man.
Rodney 2022
I know that place well and always understood that it was an Air Raid shelter for for Cane hill Hospital which was almost directly above it
Discovering of a county council tunnel. Excellent Matthew thank you.
30:00 That is not a lathe or winding machine, that is likely a vacuum deposition machine - to vaporize metal under high vacuum and create a thin film of metal on an object - you can create optical mirrors, filters, etc.
The huge column in the middle of the machine is an oil diffusion pump (creates high vacuum by boiling oil inside).
Enjoyed this just shows we dont know whats under our feet Enjoyed the added Pathe film good stuff Matt

Great video!
Half a mile away hahaha,childs imagination probably 15 feet out in the cold and damp
Another amazing one! Always makes the day better
Awesome as usual Matt
Great work as always! The best urban explorer.
Matt the Optics / mirrors places is another bunker not to far from this still in use by Optical Services Ltd. Its on the A22 by Kenley station.
I understand 5 of these bunkers were built, this one was later used a s a car workshop. The Optics was another one as @stevewalsh1987 say, that is still in use, and the one matt refers to as being demolished for housing was only partially built due to poor soil. You can find out more with some investigation on sub brit. But as always, a good video matt.
used to live pretty much opposite the one in kenley. there were quite a few deep level shelters dug during the war in this area.
There is another place which does Optics... but this place did also Im being told.
31:00 Since there are high voltage recifiers in there and "vaccum" was mentioned sputtering was one of the things these made. There was a dome on top of that carussel thing and several steps could be done in vacuum. Like finishing steps for valve production.
It's amazing how dry it is down there. Nice find.
The black painted areas are where the telescope mirrors would be examined, flat/Matt Black paint to reduce any reflected or refracted light whatsoever when examining the mirror for warpage or distortion.
Another fantastic explore
Hi Matt,you wouldn't think these places existed,very interesting video so meny bits and pieces all over the place,should open the public great tourist attractions thanks for sharing great video
What your in is linked to the big underground bunker under Epson race course. Thier are three paths Coming from different directions
I went down this 2003/4 gulf war panic for bunkers if bombs went off their used to be a air shaft also. used to be bigger when they built the new road you lost the entrance
used to be a place for motorcycles and bike repair on entrance when you walk round you sort off go round if the entrance is now gone you might not be able to walk hallway round

The flat pulleys are for a belt drive giving 3 different speeds. At 17.14 they are the 2 pedistools it sits on. That was interesting Matt. good job.
15:43 is tool holder and cross slide for a turret lathe
The two large concave discs would be fitted to the top of the machines the mirror was placed on top of the disc then it would spin to allow the tool on the metal pole to grind and polish the mirror
15:39 the hexagon shape thing is where the tooling is held on a turret lathe.
That was the best... Thanks guys. 🎉🎉🎉🎉
The machines looks like glass/lens grinders which take off microns as they rotate through a cycle and are cooled with a oil and water coolant i think
The "Machine tool" about 15 mins in is also off a lathe, probably a turret lathe
@ 30:13 is a machine for making class mirrors for telescopes. Convex coated very high tolerance optical mirrors.
This was cool Imagine the amount of Brick Masons to lay that amount of bricks Amazing!
Lol that fridge air con contraption 😂😂
What an amazing place this is, cool video matt
could be for bending pipe or metal bar
1st class video to watch thank you take care kind regards from me kenneth😮💞💞💞👍

Ward capstan lathe. Lens grinding / lapping machine Sputtering metal coating machine. Glass domes missing.

Love the old fire flash overr😁☕☕🔥👌👌
Enjoyed this one Matt. How Glen could explore in those white trainers, he's mad lol.
He buys news trainers each explore... Just kidding.
@@TheSecretVault Lol 🤣
Another great video Matt as always enjoyed this one 👍
Thanks Matt!
Yeeeha. We got massive ones of those over here in South Norwood South London. My family all used to go down them durin the war. Lets open'em up :]/
Where are the entrances?
Good idea.
I live just down the road from this place and never knew about the bunker. My dad was a patient at Cane Hill for many years in the early 80s.

Hi from Alberta Canada!!
Always a treat this place. Great vid.
At 47:30, that room is the emergency generator room. The bore to the surface would've been for fresh air in and exhaust pipe out, the concrete plinth for the generator is still evident.

The slatted concrete at intersections are access points to insert and remove heavy machinery
Hey Matt, it seems the link I posted to a RUclips video from 1960's showing the actual site when it was used for mirror manufacturing was removed by RUclips.
Liked the vlog from Margaret P
Really interesting love watching 🤗💜
Those two machines are Optical lens grinders
The black paint areas would be useful for testing precision optics.
Is that field where the old asylum used to be and if not is the old asylum building still standing elsewhere?. Would those tunnels have once led to where the old asylum was? Cool place. Once again Matt you don't disappoint your viewers x
Oh yeah! The real stuff.
There's a place more or less opposite the Kenley Hotel on Godstone rd,about 10 mins drive from here,that is still in use as a lense making place.I had to work in it many years back when i was a BT engineer.It's almost identical.I believe they used to make bomb sight lenses there during the war because it's sunk deep into the chalk cliff under Riddlesdown so there's no vibration
I’d never return to Croydon moved out 2012 😂 there is a lot of history in and around the area that still needs exploration
After all that Matthew I bet all of you were tired but the moist of it was fun!!!
Great location
Brilliant
este cara e monstro....voce e muito inteligente ...sou seu fa e seguidor!!!!
por que voce nao vai aos bunker da alemanha???
Hey Matt I was wondering if that brickwork was painted black to slow down moisture seeping in ?
A stator winder?
Fuel would not be in the other section, there would've been a day run tank on the opposite wall from the generator. There could also have been a fill pipe running down the shaft with isolation valves top and bottom.
I like his white exploring shoes.
Been on my list for a while
nice one matthew nice find any deal what year was made ? in joy watch as all your finds good thank u sir lord matthew will nite you as new king of uk ha of best youtube vids
ps new coat got on looks good
I heard of these ones when i was a kid
I'm willing to bet that room you thought was a generator room was in fact where the main ventilation fan sat and the pipe in the field was probably the exhaust vent, or possibly the intake vent.
Nice explore Matt.
There is tubes Was electric heaters there’s all over the army Camp when I was a young boy and I reckon those two big machines you was looking at was for making licorice allsorts just a thought all the best
Wish I had known u were coming hear I would of met u as I live in Selsdon and I’ve been trying to get in there and get a location for last 2years
Very cool!
Just came from watching your Heathrow training centre part IIII
Interesting explore this looks
Matt’s hitting the capital
Nice seeing you back in a bunker Matt
Wobbly fence lol hehe 😂
Yeah I agree glad they put the pipe there
1:17:45 😂
Well good
Good one!
👍👍😎
Thanks!
The tractor parts are off a standard fordson tractor .
9:30 That RSJ is in the *Wrong* place! 🤣
that tractor dont look like it was ever used and i reckon it had the engine removed and used for a genorate
I think Cane Hill Asylum was where Michael Caines brother was a patient
I just looked it up on Google and Michael Caine and David Bowie's brother's were patients at Cane Hill
The optic company used to make telescope mirrors.
7:41 - I knew a lot of the old Coulsdon mods back in the day so prob drunk with or fought with whoever put up the mods graffiti lol One chap I was locked up with in Redhill was a proper heavy bank blagger from other side of Coulsdon who was an unrepentant mod and me being a bonehead we often had a "to do" as we were the oldest of the lads spending a long holiday courtesy of being juvenile delinquents.
Vacuum evapouration coating machine, probably manufactured by CVC or Balzers
Could you use a "smoke"/rescue smoke flare to find that hole
yes
You do realise this is 6 miles outside of Croydon and you are actually in Coulsdon / Chipstead which happens to be a very wealthy and lovely area.
Exactly what I was thinking. He's standing on the main road between Coulsdon and Redhill, points at the traffic and says "Croydon"! Coulsdon's a really nice area with beautiful downs and wooded areas, I would have thought that those people would make more of an effort to get their facts right.
Matt those holes in the roof made of wood perhaps it was access to get machinery in like the big ass tractor and any outher big machinery and another thing why all the French machinery
Bloody great video again Matt you da man nice one buddy ,
The fridge can work as. Generator
I used to go down there 30 years ago, the chimney comes out in some bushes in a field.Once a couple of us went out to the field while our mates waited under the chimney and tried shouting to each other, you could hear it very faintly!
There's actually a metal chimney above it that's a few feet high so it'd be difficult for any animal to fall down.
Thank you for sharing. I had the opportunity to witness a rocket launch in 2018. Memorable experience. I uploaded a pretty cool video of the journey to my channel.
