It’s quite amazing how cities can change over time. It doesn’t even have to be that much time, you can literally leave your city for only a few years and when you come back, you’ll be baffled with the changes that occurred in your absence. Now imagine how some cities can change after ten, twenty or even one hundred years. The most drastic example is probably the beautiful city of Dubai, but we also prepared many “before and after” photographs so you could see how some of the biggest cities on the planet have changed throughout history. Enjoy.
