The small rectangular ruins (13.7m by 5.7m within walls 0.75m thick, reduced to about 1.5m in height) sit within a roughly square walled cemetery and are category B listed.
This pre-Reformation kirk is said to have been built about the beginning of the 15th century, but when the Parish was suppressed in circa 1673 when the kirk was allowed to gradually fall into ruins.
This single storey building had an entrance in both the north and south walls; in the east gable is a segmental arched window which may support a 15th-century.
The existing building appears to be of 17th-century date, however, the more substantial west gable that rises from a chamfered base-plinth with an offset at the height of the main wall-head, may also be medieval.

Records show that in 1857 the ivy-covered gables stood to their original height, but the side walls were already almost level with the ground.
Clear signs of 'recent' repairs and consolidation are apparent.
The bell was still in place in the early 1800s and was taken away, eventually being given to the Scottish Episcopalian Chapel at Ayr in 1857.
An upturned font was said to be in the west gable, although this may in fact be an aumbry or sacrament house.
