I was stationed at Herzogenaurch, Germany from 1970 to 1972 it was a secret Germán airbase during WW II. There were tunnels that would go from under the barracks and come out miles away on the other side of town, they were big enough to fit a 2 1/2 truck through with no problems. They had them gated and locked so couldn't explore because so vast people got lost inside them.

What a remarkable find. Both systems must have taken months to build. Thank you and EE for the tour, it was another job well done. I can't wait to see more of this location. Take care and stay safe out there my friends.

The tunnel systems here were unbelievable! The time and manpower to build them must have been horrific! Thanks for bringing them to us! Great trek through those tunnels!

This is an impressive find and I thank you for taking the time to share it with us. I'm especially impressed with the lack of graffiti and no real sign of vandalism.

this was so cool, you and EE always have the best ww2 videos 🙂 I shared your channel around social media to show my support, thank you both!

That was one massive tunnel system, carved out by hand. I think those cables looked like the core lead for a radio aerial, so yes, a massive comms centre. You would never think of something that big just fro seeing the front of the bunker. The first tunnel system off the street entance, you could just walk past and never know it was there. Thank you for the research and the time you dedicate to sharing history with us. Stay safe and well my friends

Wow!! What a labyrinth of a tunnel system the gift that keeps on giving! Love this when you think you have seen everything then you turn a corner and and there,s another surprise! Great respect to you HH as a single Father raising your children to discover and respect history. Like the way you and EE tested the acoustics in the tunnel ,a great duet!👍👍

Amazing tunnel and the work that had to be done , all of the tons and tons of concrete to make these bunkers ! Thanks for taking us along !

A couple of very interesting finds. The first tunnel complex has obviously been fitted out as a local air raid shelter sometime long after the war, probably for Cold War use, but the second one, apart from some graffiti, looks virtually untouched, and maybe never used. The orange dots, and yellow markings, look to be some sort of recent survey marks, as if someone has measured, and recorded, the details of this bunker tunnel system. The incoming cables look like high voltage, so maybe this complex was meant to be a hidden command centre tucked away in the hills were nobody would notice. A lot of work went into it so it was obviously important to build it at that spot. We will probably never know why they built it, but, it's still a fascinating look back into distant times. Thank you guys for sharing these hidden tunnel systems. I always love seeing these almost forgotten slices of History. Cheers to you all!

9:35 holy pancake......😅 that's a new one. Great footage btw

Wow ! Such an amazing places behind little entrances . I wonder what else could be hidden or forgotten. Thanks for showing these amazing places .

Appreciate the upload man. I was fascinated with the tunneling aspect of the bunker.

I always wonder, how you find that kind of secret places. Thanks for the really interesting tour through this one 👍🏻

Wow, you and Eagle Eyes have totally outdone yourself, Sir. I have completely enjoyed this!!!❤❤❤ please, don't tell anybody where this is at. What remarkable condition this is in!!! If you can try to close the doors back up and make it where nobody can get in - this is truly a piece of History!!! Thank you, guys!

Well, that was a double surprise! What a find! Yes, those huge cables coming into the first room were coaxial cables that would run to an antenna - I guess they had one above the bunker or quite close to it - I've never seen them so big before, it must have been for something quite special. Thanks EE and HH!

Wooow! That was absolutely nuts! It was the exact sort of military feature I love to see - a rather unassuming entrance which opens up to what seems like endless tunnels. Not only that, but with some extremely interesting artifacts still in place. I do wonder if such an extensive tunnel system up on the hill in the woods might have been a centralized communications facility. I'm guessing those thick cables coming down from above might be for an antenna array, as it has a distinctly coax look to it. I was also intrigued by the items scattered on the floor; I'd love to have been able to just sit there and sift through it all, as I'm sure there must be some very interesting clues in all that. Thanks guys!

Thank you sir !! Subscribed ! I did this as a kid in Gibraltars military tunnels before they became tourist attractions. I love it.

That was an amazing location. Thank you for sharing it with us.

Glad you made your way out, I got lost going around all those corners in the first bunker. Couldn't make out the connectors in the second bunker. They appear to be single core, could be for high power levels that cannot be managed with multicore cables. Did look like the connector end on the wall has some sort of insulator built into it which is indicative of high voltage cabling. It is similar to antenna connectors, but the cable just seems to be too big for that application. Very interesting, thanks for sharing.

Two fantastic finds. The bunker complex is outstanding. Do you have any close-ups of the connectors? I believe I know what they are, but I would like a better look. Another great video job HH. EE's sing goes well in the tunnels. So much to look at in your area. Stay safe and well out there.

Thanks for showing them.😊.

Thank you for taking through the 2nd World War bunker ❤. Such a good explore 😀.. Thanks for having us along 👍,best wishes Simon and Beth ♥️ 🙋

This was very cool ! Other than the cables , No telling what this was used for. Another great video explore guys.

Holy Pancake! I may have to adopt this. Love it. Pretty cool. It would be interesting to explore these. The grounds are lovely too. 😁

Thanks! For further exciting explorations.

Thanks! I wish I could go back in time and see this place in all it's glory. If this was for communication equipment then there must have been antenna towers around. Nice discovery freinds and thanks for sharing.

Fantastic exploration. I wish you safe travels.

Hoooooly pancake! Loved that 😂 Love the content! So cool to see these abandoned pieces of history!!

What looked like a bunker actually hid this huge tunnel system! Such an incredible find. Thank you HH and EE for bringing history alive for us ❤

Love the video, hope you and your family are doing great ❤

It appears to be a headquarters facility intended to be immune to allied bombing.

What a place , looks like something massive happened their , thank you so much for sharing

Wow....that's madness. And it's still there. Wow. Great work and eagle eyes.

Well that was a surprise indeed!! Not sure which one I loved the most lol. I will say that second bunker was unusual. It could have been for communications being set on a mountain, but wow!! Just thinking the work that was done is unbelievable. The bricks was a plus as well. Very nice in finding this for us to see. Thanks for taking us. Can't wait to see what else, as you said there is more. Stay well,safe and until then, my friend...............................................

Thank you for the walk through history...that's an awesome find

Thank you for sharing your experiences

thanks again for this interesting video, it was nice to watch again

Amazing find, Thank you!

What a discovery! Thanks for sharing and as always " Good Hunting "

Watching from mountains outside Lake Tahoe California Love your channel

Great video!!!! Thank you.

What a gigantic tunnel system and what a gigantic bunker/tunnel system!!! How many man hours it must have took to build that, I can't imagine. Awesome explore, HH and EE!❤

HI there WW2HH, I was wondering what do you think the most spooky bunker you have been in? Love your channel, I doing great work.

Thanks for filming this for us WWII buffs

Those places are amazing and a great find, I imagine there's alot more stuff down there blocked off ready to be uncovered at some point!🤔, anyway thanks for sharing and takecare!🙂✌️

Couldn't believe how big they were on the inside especially the first one. Amazing how they converted it after WWII for use. Actually found it a shame that it had now been abandoned after all that work and money that had been put into it to renovate it.

What a spectacular regabow sure spelling is wrong lol. Is the bunker system really amazing. Thank you for sharing History hunter and Eagle Eye's.

What a magnificent exploration and video

I would have to agree the large cables coming into the first room you called "Comms" to be Coax cables for Radios or links to other bunkers.

Ultra cool! Thanks for sharing your adventure. You should take a black light in.

There's alot of hours and man power put in too these structures wow the size and depths of the bunkers its amazing the length they went unbelievable

Good afternoon from Syracuse NY USA brother and everyone else thank you for sharing your adventures in history

Those orange paint marking could be for measuring or some kind of remodeling that bunker, like 3D scaning it. Amazing find.

wow another great location. well done.

I'd love to be able to get up there and see where that passage goes! You would need an extendable ladder for that and those aren't easy to carry around. What an extensive tunnel system! I can only imagine the months it took to hollow all of that out. You've got to hand it to the Germans. Extremely devoted to their missons no matter what it was. What an awesome explore! Take care and stay safe. 💖💯

Awesome show thank you

You have found there a VERY high level command and planning bunker HH & EE. I saw a generator room and fuel storage, the large room was probably the office, administration, secretaries radio operators. It all points to SOMETHING important nearby. Those cables are 'high tension' high voltage cables. Those sort of things usually went to a very tall radio antenna or a radar array above ground. 16:47 THAT is definitely a cable trench so this bunker had EXTENSIVE comms connections. Possibly even an AREA COMMAND CENTRE? If you could pinpoint on the ground above where this bunker is you might find array mountings or fixings for steel guy lines to support a radio mast. FANTASTIC! Thank you!👍👍👍👍👏👏👏👏

My goodness what a huge complex. Did you find out why Berlin wanted this built? What was it's purpose? It just stretched on and on... I could imagine something being manufactured in this large facility or maybe it was storage in a strategic location. I am just astounded at what you found and shared with us. Thanks for taking us along! Stay safe and stay well!!

I love seeing history. Thx for sharing

Wow another great video, surprising that so much is still in good condition,

This was an amazing explore! That tunnel system was huge! I've never seen anything like that before. This was definitely a surprise. I thought it'd just be a regular bunker but wow! The Germans really had this place fortified. Too bad the other was closed off. I would have loved to see where it went. Thank you so very much HH and EE. Take care and stay safe. 💖💯

You two find the best spots!

That first room in the mtn bunker with the square hole in the wall, was for a machine gunner to mow down any enemy coming in the entry you came in...the rusted steel square opening is a "gun turrett"

at 11:38 when EE starting singing a bit, i thought something was coming from inside the bunker haha freaked me out a bit

Vrhunsko stanje bunkera Hvala na objavi Klipa👍

you guys are so AWSOME!!!

That was amazing. That is cool stuff to find. If I was you, I'd buy that land by that bunker, make a museum.

Great video. Most were used for mushroom farming after the war and storage.

I used to work on communications towers. That line in the shudder room in the bunker looks like lines I've taken off of towers

Very intriguing exploration. I was stationed at Metro Tango (15km from Hahn AB) in the late 1980’s. Made some MTB and hikes to TFC Boerfink and found other sites during my time there in the former West Germany.

Thanks!

Wow, unbelievable !!! It would be nice if it were possible to see both your faces so we could put a face to the voices . Keep the great videos coming WW2HH and EE

Super Awesome!!! HOLY PANCAKE! Lol😢 with love from Florida

Great 👍 it's amazing to see the lack of spray paint graffiti. And the tunnels are so intact and not ransacked.

Great video. Love your accent. We are subscribed. We do this stuff in the Plymouth UK

very Impressive and intriguing with that entrance blocked off I wonder what is behind there perhaps you go back with a portable hammer drill and find out or would that be illegal?. Imagine finding one that has never been found with gear still in there from WW2 wow what a bonus that would be lol.

Truly astonishing how much manpower would have gone in to excavating. Could this site have been fortified communication centre. Thanks for your continued research and bringing us these fantastic locations.

Ace! That's a big find.

I was stationed at Panzer Kaserne from 1978 to 1980. I knew about the tunnels between Panzer and Patch but never got to see them.

Another incredible exploration

I think the concrete spray is to keep rocks and dirt from falling onto their poured floor. It looks like they probably kept that compound clean like a house.

The WW II Bunker on the hillside is Pretty cool. looks 100% Original wartime built.

6:20 the generator room seemed to be in a decent condition to the point id say it might be possible to run that again and see if the whole facility came back from the dead

Cool tunnel !!!

Top job guys

Hmm the open hatch with the flooded water and cables inside alone with lots of rubble makes me think there’s another level below, but was maybe destroyed on purpose to hide something underneath

Amazing😮

RF High Frequency and big power coaxial cables, either UHF Marine radar or UHF communication transceiver around 500MHz.

Just out of curiosities sake, do you wear any sort of gas monitoring device when you go into deep bunkers underground, etc? I know they would have had ventilation and things of that nature, but I imagine that there could be a possibility of toxic gases accumulating in an unused area after that amount of time. I love these videos by the way!

I love that you don’t swear. It’s so refreshing.!

these tunnels could be used for so many things

I would absolutely love to spend a weekend camping in one of these places.

Wow. A lot of work went into that..

That is crazy!!!

So epic bro I want to go here I been to a few bunkers in California.

Great Tunnels....in solid Rock. I'm really surprised the steel doors are still there and other things....some looks like fiber optic cables...lol , good looking underground airbase.

WOW! Especially, part two - great explores! The Germans were some big diggers (or their captives were). I'm not surprised to see a street level entrance to a tunnel system. Makes sense.

These tunnels are insane.. what they could create in such relatively short time period. Wish i could donate and support more.. but not in that position right now..

I've always admired the engineering feats that we accomplished during this time.

Tack!
