Rhys ap Gruffydd
Around 1164, Rhys ap Gruffydd, Prince of South Wales, conquered Cardigan and brought it again under Welsh rule, and by a grant confirmed the gift of the then existing priory of Cardigan to the Benedictines of Chertsey Abbey in Surrey. During the Clares' time, it was dedicated to the Trinity; in Rhys's time, it was dedicated to St. Mary.
