The story

Ynys Llanddwyn, a tidal island off Anglesey, is named for St Dwynwen, the Welsh patron saint of lovers. Legend makes her a fifth-century princess who loved Maelon Dafodrill; refused or rejecting him, she prayed to be freed of her love, an angel's potion turned him to ice, and God granted three wishes: that Maelon be thawed, that true lovers find happiness through her, and that she never marry. She became a hermit and died here around AD 460. The island holds a ruined sixteenth-century chapel and Ffynnon Dwynwen, her well, where a woman would scatter breadcrumbs and lay a handkerchief on the water: if the sacred eels disturbed it, her lover was faithful. Offerings made this one of the richest parishes in the region in Tudor times. Her feast, 25 January, is the Welsh Valentine's Day, and genuinely thriving.

A well that mended warts and hearts

Ffynnon Dwynwen was not the only wishing-water on Llanddwyn. The island had several springs, including one whose waters were said to cure warts — less romantic than eels foretelling faithfulness, but a reminder that a "holy" well was expected to be a general-purpose chemist, dispensing cures, curses and love-omens from the same modest puddle.

The saint who kept greyhounds off the land

A separate St Eilian's well sits near Llaneilian on Anglesey, tangled in its own legend: the saint, granted land measured by how far his pet doe could run in a day, watched it killed by a greyhound and cursed the ground so no greyhound could ever be kept there. Welsh saints, it turns out, could curse as fluently as any nineteenth-century tailor.
