Didn't Hardy set the showdown in Tess at Stonehenge?
Wow, I had no idea there were over a thousand years in the making of Stonehenge.
I tend to feel that English landscape mostly has something gentle and friendly, too, although there seem to be wild places as well - I've just not been there.

I think the 'wildest' I've been to were Dartmoor and some places in Cornwall, which were ragged or forlorn and a little spooky, but in a charming more than scary way.
I think Griff has a good point that these places have all been 'used' by humans, and that this makes a difference. This may be so long ago that it becomes a bit uncanny, but at least you get a reassuring feeling that says something like: 'someone was here before me', or, a lot more comforting, 'people come here at times'.
I could imagine that the vastness of 'unused' space in other continents would just scare me.
How old are the mounds, Lali? Are they burial places?
