From County Kerry.
Cahergal is a stone fort that possibly dates from the seventh century. It has been reconstructed as much as possible so it’s a great place to walk around and get a glimpse of history. The tall outer wall has layers of stone steps built into it, so you can climb up and get quite a view (including a glimpse of the nearby Ballycarbery Castle, as seen in this photo.) The interior smaller circle I believe was a living area.
