A span of 10,000 years spreads between now and the first possibility of settlement on the island of Eire, then swept clean to bare rock by the weight of ice. Current scholarship of the Dún Aonghasa ruins place a settlement within the inner of the four dry stone rings after 6,500 years (1,500 BC or 3,500 years ago). By way of scale, the first settlement took 30 times the duration of the U.S. Constitution ratification through 2019 and 16 times from 1,500 BC until 2019 ( 6,500 / 219 = ~30 ; 3,500 / 219 = ~16. The last state, Rhode Island, ratified the Constitution 1789).
By 700 BC, 2,700 years ago, a series of upright, closely placed stones, were erected between the second and third rings called a cheval de fries field (“Frisian horses” in English) today, this defensive structure evokes the enormous scale of the struggles around this place of defense.
This is a portion of that field, I believe, taken as Pam and I approach the inner ring entrance, walking a wide path cleared of barriers. Click the photograph for a larger image with caption.

So fascinating. Wouldn’t you love to see a computer simulation of what it looked like, Michael?

The fort in antiquity? Can only imagine, it is a wonder as it is today.

I enjoyed the flowers scattered around the rocks, and did laugh at the line under the photo. I know what you mean by the Inishmore “horse trap,” but this field looks rather like a horse trap of a different kind.

Thank you for viewing the enlarged photograph, shoreacres. The title was truncated. I did not pick that up and made a correction and edit to give more information, using the Lightroom caption rather than the title.

I agree Michael that a walk through the stones, and just being there, my senses would be like a dry sponge, trying to take it all in. Even then, the subtle nuances of the place would be missed until another visit, brought more to light. intangibles can speak volumes.

I revisit in the photographs and pull it out from there, this was a once in a lifetime visit for us. You are lucky to revisit, certainly. Thanks for your evocative comment, Dymoon.

Incredible! Couldn’t help wondering how many sprained ankles have happened while walking around those rocks. 😳
