I know it's been done before but as there are a few new posters here since last time it would be fun to go over it again, well i think so anyway. (And i'm bored)
To be honest i don't really have a theory, or have ever heard a convincing explanation.
With stone circles i can stretch to believe they were places of "worship". Longbarrows, cairns etc have an obvious function but rock art, bloody mystifies me every time i visit an example.
Anyone wanna throw their theory in the ring. ?
Btw, can we have a peaceful thread, just for a change. : )
