The apparent site of a burial ground associated with 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.
