The apparent site of an early medieval keeill or chapel, which would have been in use during the period circa AD500-AD1000. It was located on the east side of Port-y-Vullen where a cottage now stands in the plot numbered as No. 674 on the 1870 1:2500 scale Ordnance Survey map.  A Mr Cowin and others from the neighbourhood remembered seeing lintel graves ploughed up here. The large cross-slab (Manx Cross No. 69) which is now kept at the parish church appears to have been taken from this cemetery. For many years it was set on the hedge by the highroad.
