Immediately south of the Norman borough lay a Benedictine priory founded by Robert Fitz Hamon in the 1080s. In 1221 a parochial aisle was added, and other additions were made later. In the early 17th century Speed depicted it as a cruciform buildingwith a central tower. It was then under threat of undermining by the Taff and the parish transferred to St. John's. St. Mary's collapsed c1670. Little now remains at grid reference ST155803 [From The Old Parish Churches of Gwent, Glamorgan & Gower, by Mike Salter.]
