The recent Weekly Photo Challenge is about boundaries. The boundary you see in my photo is a protective barrier for the railroad network. I think it has two functions, stopping people to cross the rails and noise-insulation. What I like about the wall is that it’s not an ugly wall, I like how it’s overgrown with plants, we have other more ugly protective barriers in our city, but this one is quite beautiful in my opinion, what do you think?

The plants growing on it do make it interesting and more appealing than just a flat stone or metal wall would be. I like the low perspective you chose too.
True, it makes the barrier look a little bit natural… In TV I saw cities where they grow plants on rooftops and so on… it would make a lot of areas much more beautiful 🙂
I’ve seen those rooftop garden areas too and think it’s such a great idea! I wish we had them here.
