You are fully right and it's a pity to say that it is like that in most of the world, be it Europe or Africa, America or Asia.
Taking the pics was no problem, nobody really cares... Even taking pics from military facilities can be easily done. A smalltalk about the (objecting) guard about their hometown will usually do the job, and if you are lucky you are even invited to their home, should you ever go to that place
I guess it is some kind of naivity shared by people and gov-workers alike which brings up a homely athmosphere you wouldn't actually look for.
The artwork is modern, with ancient elements in it. I will try to post some ancient art and architecture soon...
Anyway, thanks for your nice word, the same to you
