Medieval chapel; Post medieval schoolroom. The building, which is orientated ENE-WSW, stands within a large, embanked, oval enclosure measuring 40 by 30m and raised slightly above the surrounding agricultural field. The structure is roofless, and now measures 6.1 by 3.4m internally. A depression outside the west gable suggests that the building may once have been between 3 and 4m longer.


The structural remains are of two periods, and have been interpreted as representing two different uses. 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. A piscina is built into the south wall.


The remainder of the standing structure apparently dates to around 1749, when the building was converted into a schoolroom. The masonry re-uses older stonework, but is bound together using a clay matrix rather than lime mortar.


The Manx Archaeological Survey cleared, surveyed and repaired the building in 1911, and also noted evidence of burials, interpreting these as evidence for the likely presence of an even older chapel on the site.
