25 January. Patron saint of friendship and love in Wales. Dwynwen was a fifth-century saint (died AD 460) who lived in seclusion at Llanddwyn Island. The church (the ruins of which still stand today) there was a medieval pilgrimage site and supposedly featured a magic well. Saint Dwynwen’s Day is not officially recognized in the Catholic and Anglican liturgical calendars, but its celebration has become a popular custom in Wales for lovers.
