Cantre’r Gwaelod is Wales’s very own Atlantis, and the tale is one of Wales’s best known legends. Do some features along the shore of Cardigan Bay suggests that there may be some truth to the tale?
The Lost Land of Cantre’r Gwaelod
According to the legend, Cantre’r Gwaelod was the rich and fertile ‘lowland hundred’ and sixteen cities governed by Gwyddno Garanhir, whose palace, Caer Wyddno, was reputedly near Aberystwyth. The land stretched across what is today the open sea of Cardigan Bay, and lay below sea level, protected by sea walls. The guardian of the sea defences was Seithennyn, a friend of the king charged with the all important role of shutting the sea gates every night. One night Seithennyn, who liked his drink, was at a feast in the king's palace, and forgot to shut the sea gates. It was a stormy night and the high spring tides broke through, quickly flooding Cantre’r Gwaelod, and forcing its people to flee to the hills.
The tale is first recorded in the 'Black Book of Carmarthen along with tales of Arthur and Merlin. This precious manuscript is in the keeping of the National Library of Wales in Aberystwyth.
