Crumlyn Lake, near the quaint village of Briton Ferry, is one of the many in Wales which are a resort of the elfin dames. It is also believed that a large town lies swallowed up there, and that the Gwragedd Annwn have turned the submerged walls to use as the superstructure of their fairy palaces. Some claim to have seen the towers of beautiful castles lifting their battlements beneath the surface of the dark waters, and fairy bells are at times heard ringing from these towers. The way the elfin dames first came to dwell there was this: A long, ay, a very long time ago, St. Patrick came over from Ireland on a visit to St. David of Wales, just to say 'Sut yr y'ch chwi?' (How d'ye do?); and as they were strolling by this lake conversing on religious topics in a friendly manner, some Welsh people who had ascertained that it was St. Patrick, and being angry at him for leaving Cambria for Erin, began to abuse him in the Welsh language, his native tongue. Of course such an insult could not go unpunished, and St. Patrick caused his villifiers to be transformed into fishes; but some of them being females, were converted into fairies instead. It is also related that the sun, on account of this insolence to so holy a man, never shed its life-giving rays upon the dark waters of this picturesque lake, except during one week of the year. This legend and these magical details are equally well accredited to various other lakes, among them Llyn Barfog, near Aberdovey, the town whose 'bells' are celebrated in immortal song.
