Said to be founded by Bishop Herwald of Llandaff in 1056, this lovely church hugs the side of a remote valley.
A Roman altar is built into a blocked doorway and 13th-century wallpaintings decorate the walls in the form of masonry lines, borders with chevron design and consecration crosses.
Super-imposed on these on the north and south walls are black letter inscriptions from the 16th-and 17th- centuries.
