In his book "All Roads Lead to Tallaght" (published by South Dublin Libraries), Patrick Healy says: "According to Malachi Horan this was known as Kenny's Stone from a man named Kenny who found an urn full of gold in it."
This is not the most accessible site I've been to. I won't go into the details of how I eventually got here but I can say that all my efforts were very worthwhile.
I was completely taken aback by the size of the monument. The photos I've seen of it elsewhere don't show its scale. I guess I hadn't really thought about the fact that this is a grave and that the cist would need to be big enough at least to hold an adult human body. The turned over capstone is 2 meteres long on its flat side.
This site is marked as a barrow on the OS maps. On archaeology.ie it's marked as a cist with a barrow right beside it. I believe that the barrow and this cist are one and the same. There are remains of the mound still surviving.
I loved the views from up here across the Dublin plain. Once again Howth is prominent over to the north-east.
