It is possible that they could both be true. The island slowly went under overtime but they noticed it happening and tried to fight it off and then they got hit by a wave which swamped everything inside of their defensive walls and made it pointless to try and save anymore

[@Kingofthehoothoots]

I don't know how you do your videos, just found your channel today, but I would love to hear a dissection on Vortigern and Saint Vortimer.

[@Joanna-il2ur]

The who,e of Britain is ‘Celtic’ although in antiquity nobody used the term. The so called English are typically 65-70% Brythonic and 30-35% Germanic! And the same is true for the so called Scots. So we have an interlinked history. Some of the Welsh histories take place in London, while the Welsh collection known since Lady Guest as the Mabinogion includes myths set in Gloucester. The imagined battles of Arthur include ones which would be in England. There’s a long Welsh poem called Y Gododdin which features an epic battle between the warriors of Edinburgh and those of the former Roman base at Catterick, now ‘Angles’. Wales is what is left of Brythonic ruled Britain.

I can see why Tolkien was so inspired by Welsh history, language, and myth. Everything is so old, and deep, and mysterious. It’s the kind of place where ancient oaks live in the graves of kings, and stories are written in the very wind.

[@meilir.ap.emrys420]

Its not just tolkien who is inspired by us either. As someone who speaks fluent Welsh i can honestly tell you I understand more of the elven language in The Witcher series than I do our sister language Cornish. Geralt’s name even comes from the Welsh name Gerallt. As does his elven name of Gwynbleidd. Gwyn being white, bleidd being derived from blaidd - wolf.

[@Steadyaim101]

Some psychological whiplash for me is that comparatively speaking, the Welsh mythos aren't really that old. they FEEL old though. Like Alexander the Great would be older to the Britons at the time of Anglo-Saxon invasion than the Britons are to us. We are far close in time to the original myths of Arthur than we are to the Roman emperors. Yet, the ancient Mediterranean world seems so close because we see its legacy everyday and we have primary sources everywhere. Celtic history has been so lost and fragmented that it feels like a half-remembered dream from eons ago.

[@wheat-is-an-ugly-drug]

Tolkien was inspired by old English. Hence why he wrote futhorc in his books and the homeland was called the shire. Though. Welsh and English become 1 at some point in history. Prydain.

[@MrTrilbe]

@@wheat-is-an-ugly-drug not that long ago all things considering, the word that became Wales and Welsh came from the Anglo-Saxons might have meant outsider/not one of us, and would have been used for anyone native to the British Isles, or at least not of Anglo-Saxon descent, there was also treaties between the Anglo-Saxon kingdoms to not aggravate the native British Tribes in the East-Midlands area.

[@dinofelis9343]

Here in northern germany we have a similar story, the legend of the sunken city of Rungholt. Rungholt was once the richest town in the north sea, but it's people grew arrogant and greedy and so were punished when a great flood sank the entire city beneath the waves, though it is said that when the tide is low one can still hear churchbells ringing in the deep... This story was long thought if as just that, a story. The atlantis of the north sea. But it turned out that Rungholt and its fall were very much real. The city appears on old maps and even some remains were found during low tide, and while the town might not have had goldplated roofs it likely was quite wealthy, and in a strange twist even the story of how arrogance and greed caused the citys ruin might have some truth to it as the towns people were harvesting peat, which destabilized the ground, and when a great storm came the city and most of the island it sat on were devoured by the sea.

[@CambrianChronicles]

That's really interesting, especially with the peat harvesting, thanks for sharing

[@bentilbury2002]

There's a similar Dutch legend - not surprising! The rich city of Saeftinghe in Zeeland. As with Rungholt, they were punished for their greed and pride.

[@dinofelis9343]

And for this video quite fitting is the legend of Ys, a city in brittanny which was protected by its great walls before the princess charged with protecting the floodgates was seduced by the devil into opening them with the resulting deluge swallowing the entire city with only the king surviving.

[@aquastar4336]

So interesting.

[@michaelgraalum381]

[@snopure]

As a linguist, a T transforming over time to S is not impossible. They are both voiceless alveolars, which basically means they have the same place of articulation when you pronounce them and you don't use your voice when pronouncing them. The only difference between the two is the movement of air from the vocal tract. The T is a stop, meaning minimal air is moving out of the vocal tract. The ancient Welsh T may have been aspirated at the beginning of a syllable and over time "weakened" to a sibilant S, the opposite of a stop. So the idea that Teithi Hen may have changed over time to Seithenhin is absolutely plausible.

[@meowwl]

Add in dubious dentition, with a lisp to a pronuciation, and it really isn't a stretch to imagine the one turning into the other, or vice versa, over time.

[@cooked.gaming]

Is this not one of the changes amongst the high German consonant shift? Or just my English speaking perspective haha. Better > besser Bit > bisschen

[@IsaacMayerCreativeWorks]

also Welsh, like most Celtic languages, has a long history of word-initial consonant spirantization

[@Mike-sv2nu]

it happened between German and English.

[@annemiekgroot9737]

But in combination with the word Ynis (was that it?), the T can be "swallowed", or less noticible. (Not a linguist.)

[@tlspud]

It's not difficult to imagine costal settlements, dealing with seasonal and tidal floods, would, over generations, build a series of weirs and levies to hold back the typical inundation. (Imagine modern-day New Orleans but on a smaller scale.) However, when that tsunami or 500-year storm hits, it washes away the weirs and levies, resulting in immediate and catastrophic destruction of lands at or slightly below sea level by violent inundation.

[@hedgehog3180]

You can find plenty of those in Northern Europe along the coast of the North Sea.

[@Val.Kyrie.]

We saw it happen with Fukushima. They had barriers for tsunamis, but there was (likely it seems) an underwater landslide tsunami triggered by the earthquake, which also itself triggered another tsunami. The two combined for one of those once-in-500-years events. If we didn’t have the records and science and instant communication and infrastructure we do today, it could easily have just been entirely wiped out and a legend of a village once there that was wiped into the sea. I agree that this is what we are likely seeing with these kingdoms.

[@melkel2010]

By the weirs, I wonder if they were trying to build land by capturing sediment from the rivers and fill in the area from the main shore to the islands, and the purpose of inhabiting the islands with "kingdoms" was a way of keeping people on that task. The maintenance of the retaining walls would be essential. The sandbar at the river outlet reminds me of the Louisiana shoreline, where people used to build up land with the sediments of the Mississippi river. But much of this has stopped now that the river waters are being taken up and the flow has decreased. Not enough sediment is reaching the shoreline of the Gulf and Louisiana is now being washed away substantially. I wonder if there wasn't much more land in these seas in the AD eras, protected from storms and tsunamis by a lush growth of rushes. It would be a great place for aquaculture (fish farming!) Maybe in the 6th century this is something they're trying to hang onto or rebuild from their ancient memories. A booming economy fallen prey to an encroaching sea. A loss of manpower and population to the slave trade.

[@AllisonMoon-SheWandersFeral]

We are talking about the ATLANTIC coast I mean… have you seen the waves of a regular Atlantic storm??

[@Arexack999]

As a dutchman, my soul resonates with the lost welsch. We have in living memory lost (and reclaimed!) large swatN9,ches of land to subsiding lands and storm tides overwhelming ancestral dikes and levies... some lands remain under the waves though. Estuaries are quite prone to these floods and the soft silt of estuary islands are easy prey to the rage of poseidon.

[@Alex-cw3rz]

I went to Aberystwyth University studying Geography, we were told about the Sarn Cynfelyn causeway and a legend that the bells of Cantre’r Gwaelod can sometimes be heard from the coast, which inspired a song called Clychau Aberdyfi. In Aberdovey they have a bell under the pier that rings at high tide to celebrate the legend. We took tree cores from the submerged forest at Borth / Ynyslas the trees are 4,000 - 5,000 years old and were submerged around 3,000 years ago from my memory, Ynyslas is also interesting as during WW2 they performed rocket tests there.

@@CambrianChronicles Now I'm super interested. And actually I have an old book on the history of Wales that's been on my to be read pile forever.

[@phipli]

It's a long time, a lot of upheaval (rise and fall of the Romans), plus the shrinking of a culture from a large proportion of the UK to just Wales. Imagine tales being told about Newcastle, only remembered by people who lived their lives in Maidstone, Kent. I do wonder how many tales about "Wales" are about the whole of Britain, with a cultural memory of a larger Celtic area. It's a shame England lost so much of its Celtic culture, but wonderful that Wales retained it.

[@hedgehog3180]

It's probably safe to assume that Wales isn't actually unusual in this regard and the rest of Europe and possibly the world is also littered with lost kingdoms. There's definitely some evidence of that in Denmark, the country is usually dated to the 930s with the reign of Gorm the Old but Frankish Chronicles mention a Danish king from the 800s. There's also a very rich tomb on Funen which possibility housed some sort of king but also was raided during the reign of Gorm the Old, not for its riches, lots of them can still be found, but to remove the body of whoever was buried there, seemingly with the intention of removing them from history in some symbolic way. What does make Wales stand out is that unlike much of the rest of post-Roman Europe we have very extensive sources from it, I'm guessing because it was already Christian and thus there was a clergy to preserve written history and document events. That means that in the 21st century it is actually possible to discover these lost kingdoms because clear written accounts persist and we aren't solely reliant on archeology and outside sources like in much of the rest of Europe. Extrapolating from that is pure speculation but I can't help but wonder if Wales is just a window into what the Early Medieval World was like in general, like one of those rare fossils that preserve soft tissue from an extinct species giving us a valuable insight into what it was actually like.

[@christophercappiello9788]

[@challalla]

I was reminded of the town of Rungholt in North Frisia, in modern Germany, which sank beneath the waves of the North Sea in a storm tide in 1362. If anything it proves that it is definitely possible for some destructive cataclysm to cause an entire settlement to be lost to the sea.

[@hedgehog3180]

A somewhat similar thing happened in Jutland, in 1825 a storm cut off the northern part and technically turned it into an island however given the historical precedent no one really considers it an island and it's treated as part of the Jutland peninsula. It's an interesting example of a major geographic change in recent history where popular imagination still hasn't really caught up with reality.

[@UnintentionalSubmarine]

The flooding of 1362 is known as The Great Man-drowning (referring to people rather than men) in Danish History, and based on earlier maps resulted in the loss of quite a bit of land around the south-western part of Jutland, between the islands of Fanø, Mandø and Rømø, or most of the Danish Wadden Sea area. It isn't unlikely that the rest of the Wadden Sea saw similar permanent loss of land.

[@chetw3139]

Frisia (Friesland) has a history of dikes. (Pumping the water out to make more land...etc.) Though I will admit I don't know if that comes from Dutch settlers or not. Idk. Point is, if a dike broke then they could easily lose a landmass. Side note, I've always found it interesting that what was Friesland is divided between the Dutch and Germans. With the Dutch portion still maintaining a degree of independence. (Passports, language, and killing anyone who called them Dutch till mid 1800s.)

[@GrouRocks]

@@chetw3139 wtf you're wrong in every sentence. The dikes were not by Dutch settlers at all. And the division is only between what currently is the Netherlands and Germany, it was not formally divided between two nations. While the language thankfully is fought for, the passports were just a joke from a few years back, and not taken serious.

[@LilA-zl6tf]

Reminds me of Dunwich....

[@mafiousbj]

Geologist here! Very interesting video from the historic side but also from a geological standpoint, since as you conclude this is all likely based on actual landmasses that existed. I´m not familiar with the area at all, so I can only speak of generalities, but those glaciar rock deposits that streched into the sea happen both at the sides and at the front of the glacier, the result of the ice carrying forward (ice literally flows very slowly in glaciers) big chunks of rock when it freezes (picking them up or breaking the soil/rock underneath them) then dropping them when the ice melts (that´s why it happens at the front and sides of the glacier). Usually when the ice permanently retreats these deposits form natural barriers which often form a lake or lagoon protected from the sea, at least until the front deposit is eroded or covered by rising sea levels. When this happens the side deposits can still act as wave breakers and gradually trap sand/sediments from the ocean currents, even forming or expanding existing beaches. But one big storm can erode/wash away all this sand/sediment together with some of the heavier material of the old glacier deposit, making it impossible for the beach to form again since there glaciar deposit can no longer act as a wave breaker. It also can happen gradually of course but a storm fits more with the narrative mentioned in the stories as you say. I think the "lost islands" could easily have been those frontal glaciar deposits, which being further into the sea are more eroded and not visible at low tide today like the side ones. And at the same time people back then could have seen ample and flat beaches in the area for centuries just to wake up one day after a storm and see most of it gone, adding to the tale of a sunken kingdom. Also sorry for any crude or not scientific vocabulary, English is not my mother tongue so expressing ideas in it is sometimes hard ^^

To me this bears a striking rememblance of the area known as Doggerland which disappeared quite violently after a series of minor floodings from the glacial ices that melted.

[@dominiklehn2866]

They're actually part of the same ancient landmass, that was Britain and the area around it, forming a peninsula on the end of Europa during the last ice age. So it could very well be directly connected in their causes for disappearance too

[@loke6664]

Most of Doggerland took thousands of years to sink though, it was just the final remains that sunk due to either a massive storm or a tsunami. It doesn't really add up in time with the stories here. Yeah, this was land too when Doggerland was a thing but the stories make it clear that these islands were likely remain of sand and gravel the ice left when the last ice age ended and got eroded away by storms and maybe a tsunami. The English large city of Dunwich is far more similar here, it was once the third largest city in England but after a bunch of storms most of the land it stood on had fallen into the sea. The first half of the city fell during a massive storm which sounds more similar to this story. I don't think the story would have survived as well as it did for the over 5000 years since Doggerland sunk either. Dunwhich BTW sank in 1347 AD. Considering the stories, most of the land likely sunk somewhere between 300-900 AD even if up to 1200 is possible, and some sandbanks remained to the time the first map was drawn. But of course, a serious archaeological dig by underwater archaeologists should give us enough artifacts to date if the island in fact were occupied. Until then we are still just speculating.

[@RoseNZieg]

a comment in here claimed that in one of the mentioned areas, the dead trees were dated to 3000 years ago. i have seen other documentaries used the same data so I'm assuming the 3000 years mark might be correct.

[@loke6664]

@@RoseNZieg 3000 years do sound plausible for one of the lost islands outside Wales. For Doggerland no, the dates there seems more to be around 8500 years and older. Do you know exactly where those samples are from? It is interesting and 3000 years would make it about 1500 years earlier from when the first stories were recorded which is plausible for a land with good traditions of oral history.

[@mafiousbj]

@@loke6664 i was going to comment that Dogger land sinking was very gradual but you already did it ^^ The comment about the sunken forest says this "We took tree cores from the submerged forest at Borth / Ynyslas the trees are 4,000 - 5,000 years old and were submerged around 3,000 years ago from my memory" 2000 y/o tress are not impossible but very uncommon, specially near settled areas, so unless I read the paper with the carbon dating to cofnirm it I would just take the age of "around 3000 years old" for the tress.

Ok so this is weird, but when i was younger my family had a caravan in Ceredigion.

Just an observation on Ynys Seiriol's previous English name of "Priest-holme". In Spanish, puffins are called "frailecillos", literally "little friars".

[@KaiserMacCleg]

More likely it was named for actual priests - according to tradition, St Seiriol moved to the island and became a hermit there after establishing the nearby Penmôn Priory in the sixth century, and there were later religious establishments on the island too, the remains of which can still be found.

[@redleaderantilles1263]

Folk memory is one of the most fascinating subjects for me, also the most maddening for the very same reasons I love it. It cannot ever be pieced together definitively, even with primary sources. However examining it makes us all have to reevaluate how much of history, be it recorded or not, is a matter of consensus not fact. Makes one appreciate what we know and challenge the definitiveness of that knowledge. The fact that so many historic kingdoms and figures could be several real events misconstrued, or any combination of them shows how much rides on the interpretation of whoever recorded the text we have. This is such a good example of how "corrections" can end up accidentally erasing greater context because historical writers often had to guess or work from biases just as we do. Great video

when I looked up Gwynn Ap Nudd and Gwyddno's sunken kingdom, I never realized just how deep into manuscripts, local legends, cartography, and historical events this story went into. That being said, I did find some interesting connections to other flooded lands associated with Brythonic language-speaking regions: the Kingdom of Lyonesse, usually said to be the homeland of Sir Tristan and located somewhere near Cornwall (altho wikipedia said the legend and even the name of Lyonesse isn't consistent); and the Breton legend of Ys, which sank underwater due to the machinations of the princes Dahut (kinda like how Mererid let Maes Gwyddno sink underwater).

The english and their colonial descendants really did mess everything up with their genocide and colonization. (Before anyone comes after me in the comments I know that American expansion and colonization was done by more Europeans than just the english).

[@OnlyGrafting]

A lot of the southern US explorers were actually Scottish, Irish or Welsh as they were the ones seeking to escape poverty. Can't blame it on the English. Also consider the french and Spanish quite literally owned large swathes of inland US and Pacific coast before the US itself started kicking out natives. British policies towards natives were to use them as trade opportunities for valuable resources unless aggression was displayed. American policies were to expand and monopolize the lands, removing natives through force if necessary. Blaming it on England is very silly considering a majority of the damage to Native Americans was after the US declared independence.

Very thoughtfully put together presentation thank you! When I worked in Nottinghamshire I was told a story which shows that legends and myths preserved for millennia can hold kernels of truth: A man who had worked in construction all his life told me of a small lake which had always been associated with the rumour that Roman treasure was at the bottom of the lake. I believe this was in the East Midlands somewhere. Many people had tried dredging and exploring the depths but nothing was found so it was considered a myth. Eventually a new bypass was to be built and the lake had to be drained and excavated to make the major road. A small boy discovered gold items on the excavation site and other locals came, taking some gold items home. When the authorities found out, the locals were made to bring it all back! They eventually indeed discovered a hoard of Roman treasure which is now in the British Museum and one of the more valuable finds discovered in Britain!

[@tonedeafjd]

Maybe the cataclysm of around 536 AD caused a change in the Welsh coastline. Poorly documented as it was in Roman times, the loss of a string of major coastal settlements, possibly already ravaged by coastal incursions would have then been buried by what happened to those that survived as they emerged from the accompanying climactic disaster. Fantastic video btw, thank you.

The lost kingdoms were collectively called 'y cantre gwaelod' (bottom homes of hundreds) and we're said to exist between the Western coast of wales and eastern coast of Ireland. Pwyll embarrassing himself chasing rhiannon was said to take place in these lands aswel as the explanation that bendigeidfran somehow walked to Ireland to rescue his sister. Never heard of 'Ynys teithi hen' though, it's interesting that it translates to 'island of old homes'. The wars around this time between everybody supposedly explains the original rivally between the northern highlanders(gogledd/gogs) and the southern lowlanders that still exists today in Wales. Please consider I was taught this in school so I'm going off childhood memorys. Interesting stuff separating fact from fiction.

These stories are so similar to the story of the lost land of Lyonnesse off the coast of Cornwall which I studied at university. I live in Oregon on the west coast of the US and we have a sunken petrified forest on one of our beaches. It disappears and reappears depending upon the weather. I wonder if our local tribes have any legends related to it. I’ll need to look that up. Anyway, very informative video! I love how much research you put into these!

[@kcnmsepognln]

Fascinating! Being on the other side of the country in Suffolk, we have our fair share of land lost to the sea: Dunwich and, of course, Dogger Land being the most notable. Although you did a thorough job unravelling the story, it's so complicated I'll need to watch it again, to follow the trail.

Easton ness just north of Southwold too, further east than Lowestoft's Ness point in the C16-17th. Shipden ness off Cromer. Watched hundreds of meters of land fall into the sea here over 60 years. Recently learned of a major medieval "port" at the mouth of the Deben in medieval times, the port of Goseford, not a town itslef but a collection of wharfs across several villages & different creeks at the mouth of the deben.They being Bawdsey, Alderton, Kirton & others. It was mentioned on a par with Gt Yarmouth & Kings Lynn, mentioned even when Dunwich was not. Bit OT from Wales, but my wife was half Welsh too.

[@tomlee9534]

There are similar accounts on the West Coast of Guernsey from c. 6th or 7th century of a tidal wave inundating Vazon Bay. After a decent storm, the sand is scoured back and you can see the tree trunks and forest floor exposed. I was surprised at how recent it was.

[@peterhoulihan9766]

Interesting video. Just one small note: "Low water spring" doesn't mean " the low tides of spring," it means "a low spring tide." Springs are a part of the tidal cycle where the tidal range is most extreme (the opposite being neaps). A low spring tide is the lowest tide normally experienced in the area, confusingly it has nothing to do with the season. I suspect it was named after the biblical assumption that tides were caused by "fountains of the deep." I really loved watching this because I'm fascinated by sunken lands. It blows my minds that fishermen on the dogger bank come back with neanderthal skulls and tiger bones and that you can just sail across what used to be fertile valleys and farmland.

[@CambrianChronicles]

Ah ok, thank you for the correction! I though "low water spring" looked a bit odd, but once source mentioned how you can best see the sarnau during the low tides of spring after winter storms, so I figured it must be the seasons haha

[@CrusaderSports250]

On the coast road to Drommore (South west Scotland) the road goes past a house by the sea, it used to be a farm with fields out the front of it until one night and an horrendous storm, in the morning they found all the fields had just been washed away, the family had lost their animals and land in one night, today there is nothing to tell it was there, so the islands off the Welsh coast may have had a similar fate. The farms fate although having happened a good while ago was still within living memory when I first heard about it.

[@peterjeremymckenzie8444]

So glad that you also found the Haslett and Willis paper and a well presented video. One way to understand how soft and easy to erode the material that made up these islands is to look at an area like Llanon ,where unconsolidated glacial deposits underlie the land, on the National Library of Scotland site to see how in about 100 yrs the low lying cliff has moved back about 100 metres. If islands in Bae Ceridigion where made of similar material anchored to the Sarnau with sand bars and peat marsh to the rear (like Borth Bog) then it is easier to imagine then being overwhelmed in a catastrophe. The sea in the intervening time eroding the previous land surface to a wave cut shelf. The Sarnau being more resistant with boulder clay holding the bars together to this day. The tree stumps at Ynyslas, Borth are best viewed at low spring tides after winter storms. You need to produce these for a TV audience as well, a real skill.

Hello from England, my Welsh cousin. I'm a little late to this party, but as this video appeared in my timeline, I thought I would watch and listen; I am so pleased that I did. I found this fascinating. What I liked most was the pronunciation of Welsh names, which I attempted to pronounce (mostly incorrectly by quite some margin) before the commentator. 'dd' is pronounced as 'th', how thoroughly interesting. I'm now hooked, and you have a new subcriber. Thank you for posting this. I've just noticed to the right, there's a suggested video on King Arthur whose legend I believe I am quite well versed on. I expect to be corrected and look forward to it. :)

[@pellehansen8929]

First of all thanks for the great content. As others mention in the comments, storms are entirely capable of destroying Islands. In 1362 a storm tide completely swept away large parts on the coast of Friesland (now the wadden sea in the border area between Denmark and Germany) including the allegedly large and thriving city of Rungholt. Though there are no maps from this time that can really be trusted, remains of Rungholt have been found and it is clear that the storm tide did indeed change coastal landscape of the entire wadden sea region of modern day Denmark, Germany and the Netherlands.

[@drychaf]

You refer to historically recorded events. With Doggerland dissapearing 'only' 6.500 years ago, and lots more lands gone from the coasts of now Germanic speaking regions, since they became Germanic speaking, you'd think there'd be a body of legends in the Germanic languages refering to them. I'm not aware of such legends.

[@LuisAldamiz]

But that belongs to a more flat type of landscape than the one of Wales: a storm surge can devastate and even destroy an island that is barely above sea level, what is characteristic of Friesland and the Netherlands, but hardly do anything to the rocky coastal landscape of Wales.

[@pellehansen8929]

@@LuisAldamiz I should start by saying i am no expert in this at all. You are of course right about that - a single storm will hardly have the least effect on a rocky coast. Though islands formed by build up of sand in the outlet of rivers (as seems to be the case in the video) might be a different matter - especially with the added effect of gradually rising sea levels. Of course all such claims should be based on sound scientific data, not some guy speculating from his couch (me). My point is simply that the lack of recorded volcanic/seismological activity does not necessarily exclude the sudden disapperance of these islands.

[@berlinflight_tv]

@@drychaf I'm not an expert in this by any means, but as far as I know, the end of Doggerland is usually estimated to be a bit earlier than that, somewhere between 7000 and 8000 years ago. And, at least in terms of the impact on humans in the area, it was likely not a single disastrous event but rather a gradual process where the landscape slowly turned into salty marshes over a long period of time, killing off the local flora and fauna. Since the human societies in the region at this time were, to the best of my knowledge, all hunter-gatherers (the Neolithic Revolution wouldn't reach the area for another couple of centuries), they would have followed the animals and plants into more hospitable regions long before the area sank below sea level. The gradual loss of familiar hunting grounds would have been disruptive but far less traumatic than the sudden destruction of a settlement that had been thriving in the same place for centuries, so it might not necessarily have left an easily recognisable trace in local legends.

[@LuisAldamiz]

[@JozefLucifugeKorzeniowski]

this is a good representation of one of modern archaeology's more perplexing challenges. our ancestors flocked to coasts for sustenance since before our form of hominid existed and sea levels have risen enormously since those times, so there are probably alot of important prehistoric sites under the waves and funding for finding, let alone excavating, these sites is non-existent.

Ok, having published on post-glacial sea level in Great Britain I will say the following: It's not just ocean levels rising but land subsidence that causes relative sea level rise in the southern Irish Sea. This is an ongoing consequence of post-glacial viscoelastic relaxation. A tsunami event should be detectable in sedimentary records from the relevant river beds. Tsunamis carry clearly distinct debris up the river and deposit it as a distinctive layer. There is an example of this style of feature in the Firth of Forth.

Surprised that you didn’t mention that the (almost) exact same story exists and is popular in French Britanny, as the drowned city of Ys. Obviously the legend was brought by the Britons and relocalized there, but it means the story is at least older than the 5th century.

[@CambrianChronicles]

I wanted to originally but I couldn't fit it into the already long script. Ys is super interesting although it's also extremely similar to the story of Gwyddno, it may be based on an older story but it's also entirely possible that it was inspired from Cantre'r Gwaelod

I'm sure someone has already said this but this reminds me of the Minoan eruption in the 16th century BCE that destroyed the Minoan settlements on the island that is now known as Santorini. It is also believed (as far as I am aware) that there were more islands forming the caldera around the volcano prior to this eruption but that several of them 'sunk' due to the eruption and it's effects. This is something that is thought to have inspired the idea of Atlantis. Which I find crazy as it shows how strong folk memory is and how there are a lot of these similar stories around the world that all have a little grain of truth to them when you dig deep!

[@garymaidman625]

The island of Santorini in ancient times was known as Thera. A lot of people that prescribe to Atlantis being a real place put it as Thera/Santorini. I actually believe 'Atlantis' is similar to this, a folk memory that has become an allegory.

One thing that immediately came to mind was the name Mereid and how closely it resembles Nereides, the Greek minor goddesses of the oceans.

Excellent video. I was struck by the parallels with the Breton story of the Kingdom of Ys (Kêr Ys). As you no doubt know, this involves a King Gralon who rules over a coastal city protected from the rising sea by a dike. The kingdom is then flooded when his daughter, Dahut, opens the dike (her reasons vary depending on the account, but in at least in some versions she became drunk while feasting with her lover). The kingdom is then engulfed by the sea and disappears beneath the waves. It seems clear that these two stories come from the same tradition… Was this a story that British migrants brought with them during their medieval migration into the Armorican Peninsula? Or did it develop later in Brittany based on Welsh inspiration?

[@KaiserMacCleg]

Lyonesse too, in Cornwall, another land which was once protected by dykes, lost beneath the sea in a single night. I find it hard to believe that all these stories, so close to each other geographically, could have sprung up independently from one another. Must be the same story, surely, each place with its own version.

[@CambrianChronicles]

I was originally going to include some parallels with the related stories such as Ys, but in the end it seemed to derail the video a bit, I’ll probably cover them in the future. As for the similarities, I only did some light research, but it seems like the story of Ys comes about quite a bit later than the story of Gwyddno. And as they are so similar, it was likely based on Gwyddno’s tale, perhaps brought over by the Britons like you said

Really glad you did such a deep dive into this stuff. If you're looking for other singular dramatic events that could bring about a sudden destruction, look into Phillip Runggaldier's Llyn Llion theory, of the bursting of a glacial lake in the Irish Sea, which if shown to be true bears remarkable similarity to legends. Note that Runggaldier is an amateur, and while I tend to agree with his geological argument which is in his area of expertise, he really confuses his ideas on the historical front, and I'm doubtful that his proposed event could have been preserved in such specific detail for over 13000 years.
