Basingstoke's Collapsed Canal Tunnel

The Abandoned Last Five Miles of the Basingstoke Canal is home to its collapsed Tunnel. Should we protect the Bats at all costs or can humans and Bats cohabit in a shared space?

Paul, you were absolutely accurate with your identification of the location of the tunnel collapse. I have been inside the tunnel from the Eastern portal to the tunnel blockage (about 3/4 mile in) before it was closed and I can report that the internal tunnel condition is superb (much better than a lot of canal tunnels that are in daily use today). The blockage was caused by a roof collapse in about 1932 due to a pond forming on the surface when it's drainage channel became blocked due to lack of maintenance. The blockage is a supportive plug of sand and clay which fills the tunnel from bottom to ceiling and is actually preventing any further damage from occurring. The problem with the bats is that it has been argued that the blockage has effectively turned the tunnel into a cave and that reopening it would affect hibernation during the Winter months. I have had plenty of opportunities to see bats sharing canal tunnels that are in year-round daily use by boats without any apparent problems (actually it was to the advantage of the bats in Brandwood Tunnel on the Northern Stratford Canal because they feasted on the flies driven in by a passing boat). If the Greywell Tunnel was reopened then it would allow a Marina to be built near Up Natley which would serve Basingstoke and thus provide a logical terminus to the canal, completely appropriate to the canal's function. The 'cave' condition could be emulated by closing a new Western portal by a pair of doors closed during the Winter Bat Hibernation period when any boat traffic would be light anyway. Problem is this requires an environmental compromise, the Engineering is easy and it shouldn't cost too much as most of the infrastructure already exists. Well done.

I thought it about time I offered you some feedback (read high praise) for this and the numerous other videos you've done. This one was of interest as my first job was pre-college experience as a Countryside Ranger on the Basingstoke Canal, and back in the 70s had the opportunity to take a small boat to the 'beach' at the end of the collapsed tunnel. My wife and I always look forward to your latest offerings, whether it's waterways, ancient roads, or old railway routes. We're Hampshire-based so the often local theme is a bonus. Rebecca, as an aside, my wife and I both like the side-show of what you're resplendently wearing, and the latest hair-do. Maybe a fitness video and a cook-book at Xmas will be next? Paul, you however have failed to move me on the looks or fashion front, sorry mate. Anyway, love the quality of the videos and editing, and the depth of research that obviously goes into them. And if ever you run out of new material and inspiration, do defensive stop-lines and WWII pillboxes float your boat?

[@Beatlefan67]

Our late father was born in Basingstoke, in 1913 and he'd tell us boys about the canal. I think it was a bit of a 'lads playground'. Keep up the good work you chaps - another entertaining and informative vid!

The Basingstoke Canal hidden and buried in the Basingstoke fen and under the path in eastrope towards the festival place ending at the Basingstoke street kitchen in Basingstoke is interesting too.

Good to rewatch this video! Today I went to see the ruins of King John's Castle aka Odiham Castle and walked to the other end of Greywell Tunnel. I did think about trying to find this end but as it was getting late I thought I'd just head home and watch this video!

[@andrewholloway231]

Thank you for a great video exploring the collapsed Greywell tunnel. I really enjoyed it. So, in 1991, my family hired a boat from Galleon Marine, Odiham, Hants for a short break along the Basingstoke canal. I have just visited the Basingstoke Canal Society's History, restoration and today page on their website and it says: "While returning the Canal as a navigation back into Basingstoke is beset with insuperable difficulties, it remains the Society’s aspiration to re-establish the route of this lost section as close as possible with a footpath and cycleway."

[@kevbaker153]

As said before Bats co exist in several canal tunnels that are open, Saddington on the Leicester Section has a large bat colony and they aren't bothered by boats going through it regularly

[@sidewaysaction9983]

There's been Bats in the dark room off our workshop for as long as I remember, we don't bother them they don't bother us apart from a few droppings, the house Martin's on the other hand turn up every year build amazing nests then shit all over everything but we wouldn't have it any other way. As I've said before loving your work.

To the west on the other side of the A30 there’s remnants of the canal (with stagnant water in) along the edge of Old Basing as well

[@Poultrymad]

Nice little book if you can get it, is 'London's Lost Route To Basingstoke' by P.A.L.Vine. Has some old photos & illustrations of the area including showing the route through Basing & Basingstoke wharf in 1872 & Nately brickworks (1897-1908). The big loop around Rotherwick didn't happen because the Rt. Hon. Earl Tylney objected as it cut through his land, so they dug the tunnel instead. We investigated the Western portal in the mid 1980's, also found Little Tunnel & managed to get right up to it (probably trespassing at the time!) Been a long time since we went there so very nice to see your video about it, Paul & Rebecca. ;)

[@pwhitewick]

Thank you. I'll keep an eye out

[@HenrysAdventures]

Interesting video as always! As a child I remember walking along the Basingstoke Canal from the East mouth of Graywell Tunnel to King John's Castle and on to Odiham Ford. I'm remember it being just about the muddiest place I'd ever been!

[@pwhitewick]

I can imagine that as even now its still quite muddy!

[@petersilvester1315]

Somebody else might have mentioned the pronunciation of Greywell. I lived in Basingstoke close to the line of the canal 50 years ago, and used to walk it. A very old resident I met near the tunnel told me that Greywell is pronounced as "Grool". I also heard that from other people in the village of Basing, through which the canal ran (along the castle wall). A great video, thanks.

[@boxcarjim1]

The issue with the bats is that is not a roost, but an hibernaculum - where bats over-winter. It's one of the most important hibernacula for two species of bat (Natterer's and Daubenton's) in Western Europe. The Greywell Tunnel both the eastern and western bits of it, is an SSSI for this reason.

[@harrowtiger]

Covid receptacles bats? Mmmm, tasty.

[@and7barton]

Love your channel - It would be an interesting project to research / explore the Chippenham canal tunnel (wiltshire), running between the top of Pewsham Way and somewhere along The Causeway near Causeway Close (This one is a bit of a mystery and worth researching). Another location worth looking into, is the Plymbridge railway tunnel near Plymouth. The southern end of the tunnel is a decent brick portal in some woods between Forder Valley Road and Sheepstor Road; the northern end (blocked) comes out in Plymbridge Road (on the LH side). Last time I looked, the southern end was accessible.

[@TrevsTravelsByNarrowboat]

Great one, Having lived in Basingstoke for 25 or so years in the past, it is an area I know very well, and have explored in the past. A shame you did not go the east portal as well, as you would have walked past King John's castle to get there, which would have been a nice point of interest to have added to the video. Which actually was not really a castle, but a fortified hunting lodge. I now live on a narrowboat, travelling the UK network, and I have seen bats in tunnels, and at dusk seen them leaving to go out hunting. I think we can co-exist in the same space.

[@jonathancombe9991]

Thanks a very interesting video. I live close to this canal (the part still open) and have walked the whole towpath but never explored or even attempted to explore the disused parts. So very interesting to see what it's like. Certainly the reason I've always heard is the tunnel cannot be re-opened because of the bats and they are protected. I also believe parts of the canal further west have been built on too.

[@malcolmsmith6615]

Another excellent video! The big depressions on the hill have all the characteristics of pits rather than collapses; far too wide. The tunnel almost aligns with the boundary between clay deposits and chalk deposits, either of which could have been excavated. Clay would have been useful for temporary brick works while the tunnel was being constructed. I don’t know the local history so can’t be certain. It is of course possible that all shafts were filled after construction and so none remain? Just a thought. Keep up the good work!

[@532bluepeter1]

There are more reasons than bats for not re-0pening Greywell Tunnel. the restoration of the canal as far as it progressed was an amazing feat considering the time that it lay abandoned. Like many canals though it suffers from a water supply problem. On contacting the Basingstoke Canal Authority prior to a kayaking tip I was told that powered craft have to be booked through and a warden must follow them to pinch the gates shut to conserve water supply as in the words of the staff member that I spoke to the canal is little more than a dew pond. It is a beautiful waterway and a lovely green space for local residents and a haven for wildlife but as a navigable canal it is not great. the difficulties to be surmounted at the Western end with the M3 crossing the line and a buried tunnel mean that the remainder is very unlikely so the bats really should rest easy in their roost.

Well the bats will get used to boats going through like birds get used to folks on footpaths ect so to restore I guess restore each end separately

[@catzkeet4860]

To add to this, mostly bats are happy enough to have humans sharing spaces they shelter in during the summer, BUT the issue with the use of these places where bats overwinter is that bats feed up to allow them to hibernate for several months without dying of hypothermia. ANY disturbance makes them fly around which wastes a LOT of energy. While that won't damage them, a cold snap can then leave them without the fat reserves to cope with the drop in temp, and they die. And bats are important creatures, both often rare, and vital to the ecosystem. Please be careful of bats.

I can tell you why there was a collapse..... a rather large tree was felled above the tunnel....

It's a shame bats get such bad press regarding virus transmission. They are clearly an important part of ecosystems.

Maybe someone else has mentioned it, but not read all the comments, but if Amy isnt your Sister Paul, I will eat my hat. She is a spit of you
