Australia is a young country. Most of our roads are bitumen and our footpaths cement. I found the cobbled streets and pavements of the historic cities we visited in Europe endlessly fascinating. The shapes they made, the patterns, their texture. So beautiful (but not so great for riding bikes on or wheeling luggage)
The standing stones we saw in Scotland had a beautiful patterns and features too
I loved the rockwalls that ran up and over the hills and beside the road. Many were crumbling and falling down, with wire fences to keep the stock in built beside them. But there were is a growing interest in reconstructing them in the traditional way and this was in evidence on our travels.
