Julian Cope presents Head Heritage

No, you're not :-)

The switch was deliberate, as the landforms are largely the same today as they were when the monuments were built, the landscape is anything but.

So if a stone circle is sited near a particularly prominent rock outcrop, or water source, there is at least an even change that this is significant in the placing of the monument. Whereas a monument may have been placed somewhere because there was a grove of trees that had particular "sacred" (for want of a better word) associations, or it was a place that was remembered through folk-memory as somewhere a fine herd of horses had been encountered thousands of years earlier. But we can't ever know those things, because the evidence has gone.
