Nant Gwrtheyrn is a valley in North Wales leading down to the sea.
Some time later, three monks from the nearby monastery of Clynnog were driven out of the village by stones, and as a punishment they cursed the valley with three curses: no two lovers from there would ever marry, not one of the inhabitants would be buried in consecrated ground, and the village itself would die.
And he continued to do that, according to some followed by the obligatory faithful dog, all his life. Until one day when he was an old man it came on to rain (as it often does in North Wales, he said with feeling) and forced him to take shelter under an old oak tree; at the height of the storm the tree was struck by lightening and split open, and the skeleton of his beloved Meinir fell out before him, still in her wedding dress.
Rhys died soon afterwards of a broken heart, and the two lovers were placed in the same coffin, but even there they were not to rest in peace. As the cart carrying the coffin was climbing the hill out of the valley, it hit a rock and the coffin was shaken off and tumbled down the cliff to sink into the sea, doomed by the second curse.
Parts of the village were later rebult to for a home for a residential centre to teach Welsh.
