Katowice were always considered as a dirty city with "dark" air bcos of coal.
Of course the "dark air" was made and untrue stereothype.
People from other polish cities who dont visit katowice often thinks we are still that ugly, dirty city. But i have to say, our city changed so much! We baceme more economic than industral nowedays. There are lots of green places here and modern buildings.
Also the old building were renovated and they are the part of the Museum these days!
Most of the coal mines were closed too.
