The Mound was excavated over three weeks in October 1997, by the Gwynedd Archaeological Trust. It represents a typical coastal Christian medieval cemetery in use between 6th - 16th Century AD, and covered by a sand dune.  A stone built chapel once stood on top of the mound.  All of the
original Church has been washed away leaving only the eastern side of the burial ground.  A trench was located west-east across the mound and revealed fourteen bodies, some within stone-lined cists. There were six children and seven adults. Four were recovered from the west end - a baby probably just a few months old at the time of death, who probably died from tuberculosis, leprosy or syphilis.  The other three were aged 2-3yrs, 6-8yrs, and another 18+ years at the time they died.  In the middle part were two remains probably aged 20-25 years and 16-18 years of age at the time they died. Finally 6 remains were found in the east end, one 35yrs, and others aged 40-45yrs, 39yrs, and 18+yrs at the time they died. The high prevalence of calculus in the dentitions suggested that a diet with complex carbohydrates and starchy and low in sugar.
