Cities are overfilled with architecture and places of interest. But there is a difference between architecture as a kind of art and architecture as a useful skill. Most times, places of interest are a kind of art as well. Unfortunately, we forget the interior as a part of architecute.

Street Art is a difficult topic as well because a lot of people think that its ugly and smearing. Nobody knows where it starts and what includes its. Like the red telephone houses in London are a kind of Street Art for some people, others say that it's just stuff which is needed in a city, but at the same time stuff, that is not that extraordinary. That's the reason for the category "others".

Up to this, every city has its industrial area. This could be a harbour or just a normal industrial park with a lot of factories.
