Taken from an ‘Office of Public Works’ pamphlet available to visitors some 20 years ago now. Clearly, no copyright infringement is intended. My own annotated notes may well be utter bollocks since the pamphlet text states ‘The Sloping Trenches’ and Rath Grainne are “..recognised by archaeologists as barrows”. So, Iron Age?

Thanks for posting Gladman. Just so much going on! Interesting about the cursus heading towards the Mound of Hostages. I didn't spot that at the time.
