Oh yes, I see what you are saying now.
You see, originally , I had intended this to be nothing more than a simple covered alley or street like in the background of this picture --

Then I decided to give it a little more of a fortification-like appearance, so it might pass as a town gate as well. So it does look rather plain in this role.
Thanks for the idea and the picture, former user. If I end up keeping this set, I may eventually go back and add more details.

THANKS!
