portal stone (15 feet long) lies next to the monument. A third dressed stone 4 metres long by 1 metre wide lies in front. Borlase believed this to be a distinct class of tomb - an earth-fast dolmen, so-called from the capstone's contact with the ground at the back (another example being Aideen's Grave in Howth).

Access to this megalith is through a gap in a hedge beside the Dublin Society for Prevention of Cruelty to Animals
