"By combining geophysical and topographic data it has been possible to demonstrate that the slight prominence in the north-eastern side is actually the central burial mound of an earlier ring-barrow that was incorporated into Ráith Gráinne. It too encompasses a small barrow into its north-eastern quadrant suggesting that this was an accepted custom at the time."
