Medieval chapel. The present building includes masonry of two different periods. The east gable, and a short length of the adjacent north and south walls, are thought to be of 14th or 15th century style, incorporating characteristic detailing in mullions and jambs. A Norse cross (Manx Cross 103) was re-used as a lintel above the east window, and a piscina is built into the south wall. A depression outside the west gable suggests that the chapel would have been between 3 and 4m longer, measuring perhaps 10m overall.
