Medieval chapel. The site was investigated by the Manx Archaeological Survey (1915). The structure is orientated ESE-WNW, and measures 6.4 by 3.4m internally, with a doorway in the 'west' gable; the walls are 0.4m high and 0.7m thick. The chapel has been obscured by a later structure and a well, the latter of which was sunk through the south-east corner and appears to have destroyed any trace of an altar.
