A SAND artist whose creations have graced several beaches across Wales has remembered the mythical Cantre’r Gwaelod in his latest work.

As part of the Year of the Sea celebrations, artist Marc Treanor visited Ynyslas beach to carve out his latest design, which you can see in full in the video below.

Marc said: “The original design came in a meditation and had a solid black circle."

Marc and volunteers made sure to keep a distance from a restricted area on the beach due to the ground nesting Ringed Plovers near the mouth of estuary.

“I decided to turn the disc into a cross section of a tree as an acknowledgement of the tree stumps on the sand at Borth where an ancient submerged forest is visible at low tide along the beach, where stumps of oak, pine, birch, willow and hazel - preserved by the acid anaerobic conditions in the peat - can be seen," he said.

“(It is) a wild but soft landscape combining both the spacious ocean horizons and the pull inland of the hills and the river.

“Thanks to those that came to help and see.

“And to everyone else who has played a part in this journey along the coast of Ceredigion, thank you.”

The legend of the lost kingdom of Cantre’r Gwaelod is a myth that has lived on for generations.

The land stretching out into Cardigan Bay is described as fertile land but dependent on a dyke to keep it from succumbing to high tides.

Legend has it that Cantre’r Gwaelod met its demise when a watchman appointed to look after the gates, called Seithennin, forgot to close the sluice gates.

Seithennin was a friend of the Prince Gwyddno Garanhir, and a heavy drinker.

According to this story, Seithennin was at a party at the king’s palace one night when a storm approached from the south-west.

As he was either having too much fun, or else fell asleep due to too much alcohol, Seithennin did not notice the oncoming storm, and failed to close the sluice gates. As a result, it is said the sea rushed in to flood the land, and 16 villages where drowned.

Gwyddno and his followers were forced to leave the fertile lowlands and seek a living in less fertile areas.

Radiocarbon dating suggests these trees died in about 1500 BC.
