Unfortunately, I don't know your language and I can't actually write something in the article, but I have posted a photo and the emblem of Warsaw (the mermaid) for a good beginning. I hope you don't mind.
The Warsaw article in the English JAMGuides has recently been much improved and could be of use if you had the time to translate at least part of it. There is also a nice collection of images and maps of the city at JAMGuides Category:Warsaw.
Feel free to write me if you think I can be of any help.
