As a child in England my father and Mother would take the children to a place a little like this and we would have to find our way out it was so much fun to do, but I think our day the children would maybe not find this so much fun like we did as children.
It kind of looks like someone needs to bring out the hedge clippers - it would take a lot of effort to keep this up. I remember at the Schonbrunn Palace in Vienna - the trees were shaped and there's a maze in the gardens.
The gardeners must work 24/7 to keep this in shape--the trimming, watering, and feeding. Carrying away trimmings and dead debris. My, my!
