Hi, please do not remove this and similar categories from files (and other categories) that show buildings currently located in Poland, just as you did here, here or here. As it was explained to you by another Wikimedia Commons administrator (who, coincidentally, is not Polish), this is not how historical categories on Commons work. The buildings are located in today's Poland, and therefore should be categorised just as they were.
With your permission, I am going to revert back to the old versions of all those categories and files which, as far as I am aware, represent the current consensus agreed by the Wikimedia Commons community. odder (talk) 13:38, 21 February 2013 (UTC)
