I wonder . . .

So, I am curious . . .

Why all those spikes of rock sticking out all over the place? It seems like it would be hard to balance the other rocks on top. It seem like the sticky-outy rocks would want to tilt the rocks on top . . .

I wonder if that was part of the point?

Would there be a reason to have that upward pressure against the rocks being placed on top of the pointy-outy rocks?

I know nothing about engineering . . .

PS: What's up with the smilies in the right panel (when writing reply)? It seems like they were always in the same place and today they keep changing around on me.

I can't deal with the chaos!

Maybe those are steps to stand on when shoveling the snow off the roof.

those are rocks that were somewhat bigger than the hole they fit into during the assembly process.

I'm guessing they project into the dome and are some sort of rafter support or beam. They might be projecting out to balance the weight a bit more, like a cantilevered beam. ?

Here we go:

The dry-stone walls of the clochans are almost 2m thick, square in plan, with circular roofs. Most have wall recesses but no windows. The two largest have projecting corbels inside and out that were used for securing thatch or stopping sods from slipping

Yes, you don't want your sods slipping.
