When we were in the UK recently we went to see the Uffington White horse. It's the oldest of the white chalk figures in England, probably dating from the Bronze Age. You can't really get a decent photo of it from the ground unfortunately, not even from a distance.
We went to the top of the hill and got some shots of its head, it's a very strange shaped horse!
The only way to see it properly is from the air as it's on a very shallow slope, perhaps it was originally cut there to be seen only by the gods......
This shot is from an interesting site about the chalk horses in the UK, here's the link
