When I visited Poland I found stuff like that very interesting. In particular, the large, old city of Szczecin, which was completely German for many, many years (and at times only had a few thousand Poles in it.) When I visited it seemed 100% Polish, and it was almost as if there was no trace of German anything in the whole city. This all despite the city being completely Germanized for many years and being only 2.9 miles from the German border.
