Saint Dwynwen

Saint Dwynwen, also referred to as Saint Dwyn or Donwen, is a Welsh patron saint of lovers. She is believed to have been the daughter of King Brychan and that her mother may have been Rigrawst.

According to the old tales, a young man fell in love with her but she rejected his advances. In another tale, it is she who had fallen in love with a young man but their marriage was forbidden by her father. It is said that Saint Dwynwen turned to God and prayed to him regarding her love. God grants her requests. She remain unmarried and became God’s instrument to look after all true lovers.

Saint Dwynwen retreated to solitude in a small island where she built a church known as Llandwyn. She is also the patron saint of sick animals.
