Mythical Ireland podcast 7: satellite archaeology and the closure of Cairn T

In this month's Mythical Ireland podcast, I discuss recent archaeological discoveries in Ireland from drought imagery in Google Earth and the continued closure of Cairn T at Loughcrew due to structural concerns.

The year 2018 will live long in the memory of archaeologists, historians and anyone interested in ancient Ireland. The drought of that summer, which was problematic for so many farmers, proved a boon to archaeologists as dozens of monuments became visible as cropmarks in parched tillage fields.


The discovery of a late Neolithic henge at Newgrange by Ken Williams and I on 10th July 2018 made headlines around the world. Following that, a National Monuments Service aerial survey revealed a very complex monumental landscape - features seen in our drone imagery and additional archaeological remnants picked up by the NMS photographers.

Now, in spring 2019, further discoveries are being made. Google Earth recently updated its imagery for eastern Ireland, and the new imagery dates from the time of the drought. Some images were taken on 24th June, some on 28th June and some on 14th July. A raft of previously unknown archaeology has been discovered. At the time of making the podcast, I had discovered around 50 or so. As I write this blog, my current total is 102 monuments or archaeological features, in eight counties: Louth, Meath, Dublin, Kildare, Wicklow, Laois, Carlow and Kilkenny. A majority are located in Meath and Kildare, good tillage land!

Each Google Earth map pin represents a previously unknown monument or archaeological feature.

The new features/monuments have been reported to the National Monuments Service and as I'm writing this at least 30 of them have already been added to their database and are viewable on the Historic Environment Viewer.

Two ring-ditches I discovered at Greenoge, Co. Meath, near Ashbourne, added to the Sites and Monuments Record (SMR).


The second part of the blog is dedicated to discussion of the prolonged closure of Cairn T at Loughcrew. The cairn was closed to the public in October 2018 for structural investigation and has remained closed ever since. It is my understanding that structural issues have been found, the restoration of which might be a complex, costly and time-consuming affair. Since recording the podcast, I have found out that the cairn will NOT be opened for public access on the mornings around Vernal Equinox in March, although OPW guides will be present at the site.
