@@mareli82 In Norway you can not walk on someone's field, orchard or plantation. This is because "the right to roam" does not apply to destroying someone property... Fields in in the winter time is OK (no crop damaged).
@@NeilCWCampbellif I owned a forest, I'd be happy for people to walk through there. But sadly many would spoil that freedom to roam by littering, smoking without care, fly tipping, damage and couldn't-give-a-monkey attitude dirt/quad biking, etc. And so, like many others, I would keep it as private land. If you would like true freedom to roam, you'll likely need some impressive, convincing teaching programmes to turn the don't-cares of society around.
The stone work is absolutely beautifully done. The masons who made it must have been very proud of their work. Even though it was never intended to be seen.
There wouldn't, or shouldn't, have been a need for anyone to be on a barge inside the caisson. Using barge poles (One of those things you would touch something unpleasant with.) a barge could have been pushed in at one level and pulled out at the other level. Remember that barges didn't have engines in the early days, they were pulled by horses, hence the canalside path being called a 'towpath'. Great video again by the way, that place must have been a great sight to see, judging by the level of Paul's excitement!
You wouldn't even need to to push/pull the boat in or out, if they raised the caisson an inch or so, when they were ready to leave the boat would come out itself, or conversely, lower it to draw the boat into the container.
I have lived in bath most of my life and walked past these many times on walks and been interested in their history. So, thank you for putting this fascinating video together!!!
It took me a while to understand this concept and advantage over something such as the Anderson Lift. Then I realised, when this was made, it was before steel ropes were invented and massive cast iron pillars couldn't be cast.
Fun fact: The Bends are also known as caisson disease, due to over 100 cases of the disease occurring during construction of the Brooklyn Bridge. They use caissons to lower workers to the river bed to dig the foundations.
@@andyalder7910 -- Ack -- yep, I did find a few hits/definitions of "cassion" but ultimately they are a misspelling of "caisson" -- the "caisson lock" is what Paul was describing -- which is somewhat different than the caissons used to build the foundation of bridge towers below water level (as in the Brooklyn Bridge), but yeah -- the primary word is the same. Oooops! 🙂
Always good to see people's reaction to this amazing area just south of Bath. It was the canals, railways, mines, houses, Mills etc hereabouts which first introduced me to industrial archaeology 60 years ago. Imagine my surprise cing across these locks on my bike before restoration began!
One of your best discoveries there, Paul......another fascination glance into the roots of the industrial revolution and its remaining marks still on the landscape.
Been interested in canals, railways and our industrial heritage for some time but never knew about cassions. Thanks for all your efforts you go to making these videos.
It goes to show how stone blocks are much more stable than brick walls! Oh, the ‘sluices’ are known as “Paddles”, and the associated winding mechanism as “paddle gear”. Question - was there any evidence at all on the ground of the former caisson lifts? Any depressions or masonry? FYI, lock gates only last in service about 25 years at best, and so the ones you saw were probably installed no earlier than the 1870s, 25 years before the canal closed to traffic. Fascinating, a site that I must find time to visit. Thank you for another fascinating and enjoyable video!
Interesting that the caissons idea is analogous to the Falkirk wheel. It is important to note that regardless of whether the barge was full of coal or empty the weight of the water-tight chamber always remains the same; the principle being that a floating barge will displace its own mass of water. The Falkirk wheel has two lifts at 180 degrees to one another effectively balancing each other out and so very little energy is used to perform the lift.
This system is in no way analogous to the |Falkirk wheel. The caisson is (by volume) mostly full of air and therefore bouyant. There is no counter-balanceing mass (or volume) in the water, so some considerable effort would have been required to lower the caisson.
@@nickwinn7812 The caisson was weighted, to neutralise its buoyancy, so no, it didn't take a considerable effort to lower it. That aside, I do find the analogy with the Falkirk wheel rather tenuous as it works on the principle of simultaneously raising a boat while lowering another, which is not how the caisson lock worked.
I love that characteristic of the Falkirk Wheel, using Archimedes Principle so that the whole affair remains perfectly balanced, no matter the traffic load. Letting Nature do the arithmetic, so to speak.
@@johnm2012 The up and down forces are carefully balanced in both cases. It's just that bit more obvious in the Wheel. The weight of the air (change) is negligible compared to the water displaced out of the tube/caisson that matches the mass of the barge's goods.
Hello P&R,so glad you revisited the site.The clearance work has revealed so much more than I saw about 15 years ago.I have looked at diagrams and video simulations,but I still can’t imagine how the caisson locks could have possibly worked or not,but they must have been an incredible to see.Thanks.
Great content Paul and Rebecca, one of your best. This canal has been in my 'to visit' list since you filmed about it last time. You are always igniting my enthusiasm for history, especially local history as I'm in west Wiltshire.
LOVE the long shot of the locks! Our nearby capital city has an appropriately named road with 3 locks in a row. They are marshy/wet, so not a good walk through. A nearby suburb restored their lock and made it part of a city park. Oddly, a canal was the start of two neighboring villages who merged early on to form this suburb under a new name.
Another great video, for the explanation of the lock system, and the discovery of the site we saw today. Thanks the video Paul bad Rebecca. See you on the next. Cheers mates! ❤❤😊😊
Most people in the country are not aware that there was the North Somerset coalfield and the infrastructure that was required to support it and I am sadly old enough to remember the last pit to close so this video was very informative for me
I remember the slag heaps in Radstock but then my sister's godfathers family owned the mines pre nationalisation. Just saying gone but not, yet, forgotten.
I absolutely loved this video. It brought back so many memories from childhood. I went to school not far from there and worked in the tunnel at the end of the navigable part of the Somerset CC. Used to go walking in those woods and stumbled across the locks, long before they were cleared out. My apologies for not being a Patreon at the moment - things are all rather tight. But I will carry on supporting you in whatever way I can until I’m back in a position to come back to Patreon. The offer is still there for a trip on the Thames too. Will email you about that. Fantastic footage and a great script. Thank you both.
hello again Paul and Rebecca , interesting video as always , wow the old locks were great to see , that Cassion sounded very scary lol , the pump house was so cool to see, really well done and thank you both 😊
This was a great episode, a bit like archaeology, discovering burried locks etc.. and lock gates that look like dinosaur bones. I'd love to see a full map of the canals that they built begore filling in or abandoning them to the elements.
Research Devizes lock stair (cf my avatar). In the long past, there used to be a rubber boat race up the stair, paddling across the pounds and then hauling the boat up to the next. The boats all came from Avon Rubber in Melksham.
How nice would it be to have this functional again. Down south between Edinburgh and Glasgow there had been a huge amount of work on the canals to open them to their original length. The Falkirk wheel is so popular it's astounding with their canal tours. No doubt that would raise tourism on those old canals. The locks coming down from east to west coast from loch ness down were another engineering marvel
Beautiful shots. Thank you for creating this. For those in the US who would like to see something like it, there are many sections of the Erie barge canal in upstate NY that are still intact and preserved. 250 year old amazing engineering that you can walk through and run your hands over.
Outstanding! Wow! Well done. Showing our history, the hard work and brains from years ago. Like the Guru said, "The World is at the garden hedge. Look closely, so much going on." Well presented. More, please.
What an amazing attempted engineering approach - I'm terrified just watching it. And beyond all that fun/scary stuff, this really is a fascinating exploration of what is left and what might have been.
Great video. Well presented by engaging people and narration. Having made a couple of amateur video, I’m well impressed with the filming and edits. The editing is often overlooked, it’s what makes the film with suitable audio soundtrack. Good stuff, oh yeah... I love canals as well !
Well done , very entertaining, great subject . Industrial Archeology . Enjoyed early ad for workers . Innovation and the affect early industry had on economics .
Brilliant video. I lived near the Delph locks in the West Mids for a while and it was great to have a peak when they were drained for repairs. I suppose this is a greener version of that in a sense! Going on the to visit list!
WOW ! absolutely brilliant, words cannot express what you have found and the history is enormous, a great shame that this will never be used again....GREAT WORK
@Paul and Rebecca Whitewick about 20 years ago by this point. I have a badger skull that I found nearby that I took as a souvenir. When we uncovered the arch, the ground was so unstable we had to plan rescue contingencies incase the first in got trapped. We were originally looking for the actual site of one of the Cassion locks, (the locations are still lost to this day) we had a hypothesis that their above ground structure was reused to form the base for the engine/pump house - but although close - the measurements didn't match those recorded.
Another amazing video. What a research. Thoroughly enjoyed this. Well done. Thank you so much for sharing this with us. Ps. Your face is a picture at times Rebecca.😊
Lovely find in Engine Shed Woods!! Well worth reading the book "The Map that changed the world" which tells the story of William 'strata' Smith who surveyed this canal, I wonder who had a go at designing that casson lift and who got the job of testing it ..... Great video, great to see Rebecca out again. Good luck from Spain!!
Wonderful video. I used to keep our narrow boat at Brass Knocker Bottom Dundas yard near Monkton Coombe which I believe was part or the S&A Coal Canal. I live in Salisbury and love your ventures out as they are all in striking distance for me too. Keep it up, your output is fascinating.
For a bit more of an insight into the Somerset Coal Canal and this part of the Industrial Revolution, viewers might wish to read "The Map That Changed The World" by Simon Winchester. It tells the story of William Smith, the man who carried out the geological survey for this canal and who can be regarded as the father of geology.
It also notes that it was the last time that Britain could truly feed itself (though it is a bit inverted because prior to that it was Death in the cold winter that regulated the need to produce food..)
*caisson (pron. "cay-s'n"). They did actually become a thing, but not in this terrifying submarine manner. They were built in pairs and lowered down the slope full of water but open to the sky and counterbalanced by the twin caisson coming up the slope.
Absolutely brimming with history and simply oozing past spirits and the vibration of so much life. That area won't ever be like some others, it is permanently saturated with, - well l don't know what it's called but you two must know what I speak of. 👍😎
Nice video you two. You can see how short of water they were, the canal locks are so narrow compared to the old locks near me in Bolton at Nob End. And yes that is the correct name, there are plans afoot to fix the old breach on the canal, so maybe they will be filled with water again someday. Mind tyou there is a lot of controversy over building houses near the site but the developers are supposed to be footing the bill to repair the breach. Chris
By all accounts Paul & Rebecca the inclined plane at Coombe Hay was like the inclined plane on the Tavistock Canal As it never carried boats with the cargo being carried in a wagon running on rails. From memory it was mainly single acting with the loaded wagon (presumably full of coal) hauling the empty wagon up. It had a short life between the failure of Robert Weldon's Hydrostatic Cassion Lock and the building of the Combe Hay Flight. The Somerset Coal Canal Company never raised enough money to build the locks on the Radstock Branch so it remained unconnected and of course was ultimately replaced by a tramway.
A beautiful location. Ruines of the old locks in nature. You two are a lot of fun to look and follow. Just wondered you might have digged Rebecca, as she disappeared for a while. 😅
I knew the moment they used the words "canal" and "terrifying" in the same sentence, that there could be only one such contraption they were referring to: the dreaded caisson.
Very interesting video, and some lovely stonework and industrial architecture on display there. Keep it up. I love canals. Quick point of order, though - it's a caisson, pronounced "case-on" and not "cass-on" or "cass-i-on", it's a word taken from french meaning "large chest". No, not that sort of large chest, get your mind out of the gutter. Literally referring to a bloody great big airtight box you could put a boat into.
Quick footnote: The entire canal sections here are on private land (We were unaware of this at the time as the signs had been vandalised). The Trust are in the process of redoing them. So please do avoid walking in between them!

@@mareli82 In Norway you can not walk on someone's field, orchard or plantation. This is because "the right to roam" does not apply to destroying someone property...

It's something else isn't it.
That’s the difference between someone who is good at their job, and someone who is a master at it

You two are a lot of fun to look and follow. Just wondered you might have digged Rebecca, as she disappeared for a while. 😅
Thanks - great clip and fascinating waterways-
I knew the moment they used the words "canal" and "terrifying" in the same sentence, that there could be only one such contraption they were referring to: the dreaded caisson.
Love the 'Studio' bit in the video but really interesting as well.
Very interesting video, and some lovely stonework and industrial architecture on display there. Keep it up. I love canals.
Quick point of order, though - it's a caisson, pronounced "case-on" and not "cass-on" or "cass-i-on", it's a word taken from french meaning "large chest". No, not that sort of large chest, get your mind out of the gutter. Literally referring to a bloody great big airtight box you could put a boat into.
Great video, and I love the wholly hats.
Another brilliant video. Thank you 😊
One of your best ever. really interesting!
