The legend

Cantre'r Gwaelod was an area of land which, according to legend, was located in an area west of present-day Wales which is now under the waters of Cardigan Bay. Accounts variously suggest the tract of land extended from Bardsey Island to Cardigan or as far south as Ramsey Island. Legends of the land suggest that it may have extended 20 miles west of the present coast. There are several versions of the myth. The earliest known form of the legend is usually said to appear in the '' Black Book of Carmarthen'', in which the land is referred to as . In this version, the land was lost to floods when a well-maiden named Mererid neglected her duties and allowed the well to overflow. The popular version known today is thought to have been formed from the 17th century onwards. Cantre'r Gwaelod is described as a low-lying land fortified against the sea by a dyke, Sarn Badrig (" Saint Patrick's causeway"), with a series of sluice gates that were opened at low tide to drain the land. Cantre'r Gwaelod's capital was , seat of the ruler Gwyddno Garanhir. Two princes of the realm held charge over the dyke. One of these princes, called Seithenyn, is described in one version as a notorious drunkard and carouser, and it was through his negligence that the sea swept through the open floodgates, ruining the land. The church bells of Cantre'r Gwaelod are said to ring out in times of danger.

Relationship to myth of Llys Helig

Rachel Bromwich raises questions over the location, stating: "There is no certainty, however, that in twelfth century tradition Maes Gwyddneu did represent the submerged land in Cardigan Bay." She also links Gwyddno Garanhir with the Old North, not Wales. She further discusses a similar tale, that of the submergence of the kingdom of Helig ap Glanawg in the Conwy estuary. As with Cantre'r Gwaelod, there are tales of remains being seen of the sunken kingdom ( Llys Helig). Bromwich believes that the two stories influenced each other, and that "The widespread parallels to this inundation theme would suggest that the two stories are in fact one in origin, and were localized separately in Cardiganshire and in the Conway estuary, around two traditional figures of the sixth century. She also notes that J.O Halliwell in his 1859 text ''An Ancient Survey of Pen Maen Mawr'' gives Helig the title "Lord of Cantre'r Gwaelod". In the book ''New Directions In Celtic Studies'' Antone Minard wrote that "The Welsh legends of Cantre'r Gwaelod and Llys Helig (Helig's Court) contain the same details of audible bells beneath the waves and ruins which are visible at the equinoctial tides, which are the anchors of credulity in the story".

Relationship to myth of Teithi Hen

In the tale of Culhwch and Olwen, one of the Welsh Triads, one of the men at Arthur's court is named as Teithi Hen ap Gwynnan, whose land was inundated, and only he escaped. He is also mentioned in Cronica de Wallia, part of the Annales Cambriae, and the lost land is called . This legend has similarities to Cantre'r Gwaelod but there is no direct connection with Seithennin. The location is placed west of Dyfed, or between Anglesey and Ireland.

Physical evidence

There is no reliable physical evidence of the substantial community that according to legend lies under the sea, although there are several reports of remains being sighted. In 1770, Welsh antiquarian scholar William Owen Pughe reported seeing sunken human habitations about four miles (6 km) off the

marked the coastline of Cardigan Bay in the same location as it appears in modern times, suggesting that the flood occurred before the second century AD. The "causeways" described by Lewis can be seen today at beaches around Cardigan Bay. Known as , these ridges stretch several miles into the sea at right angles to the coast, and are located between each of the four river mouths in the north of Cardigan Bay.

'', visited Sarn Gynfelyn. The programme also showed the remains of the submerged forest at Ynyslas, near Borth which is associated with the lost land of Cantre'r Gwaelod. The vista of dead oak, pine, birch, willow and hazel tree stumps preserved by the acid anaerobic conditions in the soil is revealed at low tide; storms in 2010 and 2014, and particularly Storm Hannah in 2019, have eroded the sea-bed offshore and revealed more stumps. The forest is estimated to have been submerged between 4,000 and 5,000 years ago. Evidence of human habitation includes a timber walkway made of coppiced branches and upright posts, human footprints preserved in hardened peat, and burnt stones thought to be from hearths. In 2022, geographer Simon Haslett and linguist David Willis published research suggesting that the medieval Gough Map provides evidence for two offshore islands within Cardigan Bay. These were suggested as "likely to be the remnants of a low-lying landscape underlain by soft glacial deposits laid down during the last ice age which has since been dissected by rivers and truncated by the sea".Neil Prior, "Map may show evidence of Wales' Atlantis off Ceredigion", ''BBC News'', 21 August 2022

Origins of the myth

The myth, like so many others, may be a folk memory of gradually rising sea levels at the end of the

. The physical remains of the preserved sunken forest at Borth, and of Sarn Badrig nearby, could have suggested that some great tragedy had overcome a community there long ago and so the myth may have grown from that.

Analogies in other legends

The legend of Cantre'r Gwaelod is comparable to the deluge myth found in nearly every ancient culture and it has been likened to the story of Atlantis.

Geologist William Ashton's 1920 book, ''The Evolution of a Coast-Line, Barrow to Aberystwyth and the Isle of Man, with Notes on Lost Towns, Submarine Discoveries, &C'', discusses the legend and takes Ptolemy's map as evidence of the existence of an area of lost land in Cardigan Bay. Ashton also includes a conjectural map of Cantre'r Gwaelod within the bay.

. Cantre'r Gwaelod is central to the setting of the 1977 Newbery Honor Book '' A String in the Harp'' by Nancy Bond. The kingdom also plays a major role in '' Silver on the Tree'', the last book of '' The Dark Is Rising'' by Susan Cooper, parts of which are set in Aberdyfi. Siân Lewis and Jackie Morris's book ''Cities in the Sea'' (2002) retells the legend for children, and Welsh musician Cerys Matthews's first children's book ''Tales from the Deep'' (2011) features a story, ''The Ghost Bells of the Lowlands'', which was adapted from the legend of Cantre'r Gwaelod. Ava Reid's book A Study in Drowning features themes from this legend, the chiming of the bells under the water, the Welsh folklore and the there is even a place called the lowland hundred featured in the book.

(" The Bells of Aberdovey"), popularised in the 18th century, relates to the part of the legend about the bells being heard ringing beneath the waves in the town of Aberdyfi. This song inspired cultural projects in the town involving bells; a new chime of bells was installed in September 1936 in the tower St Peter's Church, Aberdyfi, specifically designed to allow the playing of ''The Bells of Aberdovey''. An art installation by the sculptor Marcus Vergette, a bronze "Time and Tide Bell", was mounted beneath the jetty in Aberdyfi Harbour in July 2011 as a homage to the folk song. The bell is rung by the action of water at high tide. The story of Cantre'r Gwaelod was the theme of the song entitled "Y Bobl" that competed in the final of Cân i Gymru 2021, which was written by Daniel Williams and performed by Lily Beau.
