They have to fence it off because it's so accessible. Tell you a story… We were visiting Isla and missed the bus to the Ardbeg distillery. A one-eyed old boy (Mick) overheard me moaning and offered to drive us – cool!
After the tour, we had lunch with Mick then he suggested we visit the Kildalton Cross nearby. I'd read a little about it and it was a sunny day so agreed. He drove slowly and stopped by a little deserted churchyard. My jaw hit the floor and I was misty eyed (I am just thinking about it)!
I stood on it, touched it all over, embraced it. It's the most beautiful man-made thing I've seen and it's 1200 years old. And it's just standing there quietly and uncelebrated in that little churchyard
