The popularity and celebration of St Dwynwen's day has increased considerably in recent years, with special events, such as concerts and parties, often held and greetings cards printed. Although still not as popular as St Valentine's Day in February, St Dwynwen is certainly becoming better-known among today's population of Wales
The story goes that Dwynwen fell in love with Maelon Dafodrill, but unfortunately her father had already arranged that she should marry someone else. Maelon was so outraged that he raped Dwynwen and left her. In her grief Dwynwen fled to the woods, where she begged God to make her forget Maelon. After falling asleep, Dwynwen was visited by an angel, who appeared carrying a sweet potion designed to erase all memory of Maelon and turn him into a block of ice. God then gave three wishes to Dwynwen. First she wished that Maelon be thawed, second that God meet the hopes and dreams of true lovers and third that she should never marry. All three were fulfilled, and as a mark of her thanks, Dwynwen devoted herself to God's service for the rest of her life.
Dwynwen became a nun, fulfilling her wish to never marry, and left for the island of Anglesey to build a Church. This is referred to as Llanddwyn, literally meaning "Church of Dwynwen". Remains of Dwynwen's church can be seen today on the island of Llanddwyn, off the coast of Anglesey. Also situated on the island is Dwynwen's well, where, allegedly, a sacred fish swims, whose movements predict the future fortunes and relationships of various couples. Visitors to the well believe that if the water boils while they are present, then love and good luck will surely follow.
