If you are planning a visit and want to be free of Muslims, head to Poland
Wroclaw was destroyed in the war. Why are you recommending it as a tourist destination? I’ve been there a few times. Certainly not worth an excursion. Although, it is probably the best spot in Poland to practice your German.
Or the Panorama Racławicka
Actually I hear more spanish there rather than German - in Poznan and Szczecin there's a lot more German - around that area you also have German auto factories.
Though of course you can skip Wrocław - I personally prefer Toruń to both Wrocław and Kraków, or even lovelier the Bieszczady mountains
