Medieval chapel. The investigation of the chapel is described by the Manx Archaeological Survey. The building is orientated east-west and has internal measurements of 5.7 by 1.7m. It has turf capped walls 0.8m wide with an average internal height of 0.7m. The doorway is in the west wall. A small recess was built into the east wall, near which was found a stone thought to survive from the altar.


Trenches through and around the building confuse interpretation, creating a sense of a second 'wall' closely surrounding the structure on all sides except for the north-east corner.


No clear evidence for an enclosure or burials has been recorded.
