The monument comprises the remains of a small medieval chapel. It is situated on top of a small hill within an oval earthwork enclosure probably of late prehistoric or medieval origin (Scheduled Ancient Monument: Chapel Hill Camp, GM248). The chapel itself lies within another curvilinear possibly ornamental enclosure at the north side of the earthwork. It is a single celled building aligned east to west and measuring 8 x 6m with the gable ends standing to c 6m; there is no roof. Near the west end of the south wall is an arched door and towards the east end a small window. In the middle of the east gable wall is a large window with a central mullion. The west gable is surmounted by a bellcote. The remains of two early Christian inscribed crosses (Scheduled Ancient Monument: Merthyr Mawr Stones, GM026) are situated within the building, this is not their original location.

The monument is of national importance for its potential to enhance our knowledge of the organization 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 area around them within which related evidence may be expected to survive.
