Also, do you think all structures like this have got similar non-tomb intentions? So if you went to, say, St Lythans (only because that's somewhere I've been) that to me looks superficially similar, would you expect to find the same clues to support your Trevethy theories? That would help your argument would it not.
You'll have to excuse me for not knowing exactly what clues you're talking about because the other thread got a bit too muddy.

Specifics, that's what'll convince people a bit more. And comparisons with other places?
