One thing you can count on around the world is street art. No matter where you go, you will find graffitis of all kinds. Ugly street gang tags or beautiful murals, or sometimes tiny little paintings on a forgotten wall.
You can find beautiful pieces all over Berlin, no matter where you go. I’ve only been in Berlin two months and have found many by simply wandering around, though most I forget to take pictures of. Rest assured, I will be updating you with many, many more as I find them.
