The chapel is orientated WNW-ESE. In 1885 it was described as measuring 5.8 by 3.1m internally, with walls 1.8m high, and a doorway towards the east end of the 'south' wall. In the 1920s and 1930s the structure was reduced almost to foundation level and rebuilt. Its dry stone walls are now 1.3m high internally, 0.5m externally and are 1m thick. There is an entrance 0.5m wide in the SW wall but no visible trace of an altar.


Finds include Edward I silver coins recovered from near the base of a wall, a hollowed boulder, a perforated slate disc, and a perforated slate slab.
