The Tunnel in a Derbyshire Village with an unusual past - Mystery Solved! 

It almost looked like the tunnel could have been a narrow guage railway. But it was nice to hear feedback from a local. Beautiful find. That water looked so inviting but, as you said, very dangerous. Thanks for sharing, Ant. Another great video.

Derbyshire has so much 2 see & discover.I love its diversity.Thanks Ant.😂

Thank you for the underground tour this day. The walking tour is also intriguing as the underground one. Appreciate the time involved with these. Puts a smile on my face, which is a rarity this past year and half. Enjoy the week ahead and see you on the next. Cheers Ant! 🇬🇧🙂👍🇺🇸

More amazing finds in the Derbyshire hills. Especially that old piece of track. Very enjoyable as always. All the best.

Great video, my grandad worked in the Hoffman Kiln just before WW2, used to go wandering around there all the time!

The tunnel is an airshaft that took air from the escarpment face into the base of the now defunct Hoffman kiln. Its an air intake not an exhaust.

Excellent - another trip only a mile or so away from my house!

Good call about the lagoon, deep and dangerous, surprised it's not cordonned off. Had to be water related - too many twists and turns for tramway.👍👍👍

The blue lagoon water looked so inviting for a swim, but I think I'll look from a distance. LOL LOL LOL Ant another great watch, thanks for helping to keep history alive.

The entirety of Harpur Hill is a mystery wrapped in an enigma, so much to look at up there. 👍

I got worried about Ant clambering in that old, small tunnel, interesting though it was!

Wow that was great. That tunnel was awesome, just loved the trek through. Love this history thanks Ant. Please take care

Thanks Ant. I really enjoyed today's walk and tunnel explore. Keep up the great video's.

Great video as always! You should use them map / landscape fades a lot more as they explain things a lot better :)

What an interesting tunnel! Loved the little bridge too. You certainly know where to find things, Ant!

The various water works going down hill almost look like settlement lagoons to take fine contamination out 🤔 although the water would still be bad for wildlife etc but i suspect its PH was least of their worries in those days … Interesting stuff 👍🏼

What an amazing explore. The scenery and blue lagoon great find. What an enjoyable day you must have had . Thank you for all your research and filming. Brilliant work.

Quality as always another fantastic explore top man👍

Cracking video again Ant!!

Great video, very interesting.👍

even though it was from a tunnel it was a nice bit of fascinating history

Brilliant. It's fascinating what turns up across the countryside, just a relic now of what was once probably a hive of activity. Well done Ant and thanks once again.

What a fascinating industrial landscape, there, Ant. And i also find the cromford and high peak railway fascinating too. Im told that high peak has nothing to do with peaks, as in mountains! Ive walked along the cromford canal in the past

nice video... I once discovered an abandoned train track. I Was about 12yrs old living in a bnb in south Croydon and decided to explore and what I found was some very old tracks just out of the back of peoples gardens and a bridge i walked under i was actually on, it was amazing 😀. I still drive under that bridge 30+ yrs later and think about it. We used to get as close to the south Croydon junction as we could to listen to the inter city trains as they jetted past they were very loud. On a nice day it was a nice walk wonder what it's like now.

Excellent, very interesting video. That blue lagoon must be very deep and judging by the lack of vegetation, is probably toxic. There must be many such overflow tunnels from old quarry workings. What's amazing is how well constructed they appear - and how large.

thank you ant .that was very good video as always i dont know how you manage it it must be the way you edit your videos but when you were inside the tunnel i felt that i was with you walking alongside you. once again many thanks

really INTERESTING. . Thank you

Fascinating. I’m so interested in old infrastructure, I live in castleford so there’s a lot of old pit works, railway etc but I genuinely do want to start venturing out more. Nice video you really do include us on your journey. Take care bud.

Great explore Ant. Thank you.

Brilliant again

Nice one .. .. ..possible air feed for a lime kiln?

Interesting video. Enjoyed watching ❤

As enjoyable as always.... enjoyed your vlogs from the North Yorkshire Coast as used to holiday there years ago!...I live near Beccles, Suffolk and if you walk from Beccles Quay along the Angles Way for a short distance there are the concrete remains of the old Railway line Swing Bridge and a former Signal Box that is now a Pumping Station!👍

I think that is for water. For a start, the entrance is too far from the kilm and the gases would have had to go downhill first. Ahh, looks like the recess heads to a natural cave to perhaps using that for extra drainage. If it had been a flue, granted the brick works seems to be stained, but the natural rock part would have been even more stained with all it's recesses for the smoke to gather in. Recess possibly made for people to get out of carts during construction and natural drain and added bonus. Appears to be a lot of marks from carbide lamps. There was a reservoir up on the hill, possibly a connection between that and the lower one showing on the old maps? Ahh, watched to the end, was mostly right, was for water :)

That blue lagoon has is incredibly caustic due to waste from the quicklime process and the chemical weapons disposal from when the RAF used it as a chemical weapons storage. Despite it being very dangerous people love to ignore the warning signs and bathe and swim I've seen families encourage their young kids to swim in it. This is why in the first arial picture, it's black, because the council died it to discourage swimmers.

The Blue Lagoon looked an incredibly scary place to me. Is it poisonous because i would have thought there would be birds near water. i get concerned when you are underground, but your tunnel photos are the best.

Really interesting! Why is that lagoon so blue and dangerous though, don't think you said? Also, you have a lot of guts walking the entirety of that tunnel not knowing what it was for or where it lead!! Hope you do inform someone where you are going beforehand, it could have been hazardous! Great job though.😀

We can see you're not the only one who's been right to the end of that tunnel for the discarded food wrappers. But that being said it's in remarkable condition for it's age

Good video

great video again Ant , i will have to go have a look myself now , the blue lagoon looks so inviting but is polluted to hell , do you let people know where you are going in case something goes wrong ? was just a thought i had when you were in that tunnel , keep safe , keep them coming 👍

hello ant have you ever thought of doing minera quarry here in wrexham they quarred for limestone

Old drainage tunnel

another gem Ant

Harper Hill was the sight of some ww1 training trenches and is now home to the health and safety executive. There is a London tube train in a tunnel up there that was used to investigate 7/7 tube train attack.

Interesting video, could it be a water drainage tunnel or a worker's access tunnel so they didn't have to walk from the villages either around or over

Do you know if there is a river/canal in the village directly opposite and down hill of the portal?

But how did you managed to find this Tunnel in the 1st place Ant??? Also @ 19:45 - I've cycled over that little bridge that you have found along that Track bed b4!!!🤔🚂🚂🚂

Hi ant, what is the background music you used?

Another excellent video Ant .Does anybody have any idea what would cause the water to be that blue colour could it be copper just a thought.

Time to use LiDAR

An easy watch, I can’t not watch a video with tunnels

Could house umpteen migrants in there

Boring, Boring 🏴󠁧󠁢󠁥󠁮󠁧󠁿

As if you didn't climb that fence 😂
