[1] The chapel is oriented east-west and is constructed of local grey limestone rubble, with red sandstone entrance and window dressings and quoins, and a stone slate roof.

A Bathstone cross erected in the mid 19th century by the Marchioness of Bute[2] stood on the east side of the roof, but this was removed during renovation work.

The floor of the chapel retains its natural unhewn bedrock, which shows considerable signs of wear close to the entrance, indicating many years of use.

Its floor being composed of unhewn natural bedrock is taken to suggest that the chapel was so sited due to a religious vision being reported, resulting in the sanctity of the bare rock being respected and thus left uncovered.

A guidebook of 1793 reports that 'The Tor Chapel, perched on the summit of the ridge of rocks, once an appendage of the abbey before us and as it has not been desecrated it is sometimes visited by Roman Catholic crews of the ships lying in the bay.
