Dydd Santes Dwynwen, literally "St. Dwynwen's Day » is considered as the equivalent in Wales for Valentine's Day and is celebrated on January 25 of each year. It is celebrated in honor of Dwynwen, the Welsh Saint of love so that date is the day of the feast of Saint Dwynwen.
Throughout Wales, children and adults write their letters to give to each other in celebration of their love, or sometimes without a name in order to attract the other person in love.
Much of the history of Wales is based on stories and songs, since it was considered a virtue not to write these stories and verses, but everything was oral. As such, the original tale has been mixed with elements from Celtic folk tales and stories.
Dwynwen lived during the 5th century AD and was one of the 24 daughters of Saint Brychan, a Welsh prince of Brycheiniog. She fell in love with a young man named Maelon, but rejected his loves. This, depending on the story because it was she wanted to remain chaste and become a nun or because her father wanted her to marry someone else.
Dwynwen became known as the Saint of Lovers and pilgrimages were made to the island of Dwynwen where she has a church for pilgrimages.
