This monument comprises the remains of a medieval chapel built in the twelfth century. It is single cell and was largely rebuilt in the fourteenth century. The south doorway is partly original; the upper walls and the remaining openings are fourteenth century. The west wall rises to a gabled bellcote. The sixteenth century south chapel is built over a burial vault, roofed in stone slabs and entered by a flight of steps from the east end of the main chapel. The chapel was appropriated to Plas Lligwy, now demolished, until the start of the eighteenth century after which it went into disuse. The walls stand to their full height but the roof is gone.

The monument is of national importance for its potential to enhance our knowledge of the organisation and practice of medieval Christianity. The site forms an important element within the wider medieval landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, layout, building techniques and functional detail.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
