I have a weird curiosity about it. Ever since i saw a few videos online about places like Blackpool or Port Glasgow in the UK, i have been thinking if there are places like that in the remaining european countries.
I thought about Gelsenkrichen in Germany or Bydgoszcz in Poland.
If you know why those places have turned out the way they have, please do tell me. But i intend to look into their history myself anyways.
