It scares me how some of you see Poland, seriously we're not a third world country, bit behind the West, but its still Europe...
However, answering some of the question that have been asked here: Poland is a VERY homogeneous country. I think 98% of the population is ethnic Polish and also a majority is Christian Catholic. That's because the communists moved hundreds of thousands of people after WWII to fit the new borders (most have nothing to do with our history, just Stalin's random ideas). Also, communists suppressed individualism and pretty much everything that did not fit the Party propaganda, so many local features and traditions have been lost. A good example are accents: a Londoner can tell whether sb is from Manchester, Birmingham or Glasgow simply by how a person speaks. I would not be able to do so, since everybody speaks in the same way.
Finally, a word to the OP: Wrocław is a brilliant city, I spent 2 weeks there during these holidays and enjoyed it very much
Though, I have to say that it looks very German (and it actually used to be).
