That's interesting, wideford. I don't think I've heard about such aligned stones before. I wonder if it was an aesthetic thing. or something symbolic that they were facing each other. Or (now in the realms of wild speculation) to do with sound? How far apart were your Scottish ones? These are eight metres - I guess that's quite a distance. hm.

On the subject of the springs, I guess you're right - there are a lot of springs in the world and you have to put your stones somewhere. It was just the double nature of the springs that took my attention. Though they may be much more recently sprung up than the stones of course.
