When the mayor of Sao Paulo passed a bill placing a ban on outdoor advertisements, locals worried their city would look dull and bland without the splashes of color that advertisements brought to the streets. They needn’t have worried. Instead of tacky ads, the city’s neighborhoods are now enlivened by a dazzling street-art scene featuring some of the world’s most famous street artists, including Os Gemeos.

Berlin is a city where the graffiti is not just interesting to look at, it also has deep historical significance. After it was erected in 1961, the west side of the Berlin Wall became the largest canvas in the world, attracting artists expressing messages of peace and protest alike. The east side remained blank. After the wall fell, artists rushed into East Berlin, claiming the formerly military-occupied areas for themselves. Today, street art in Berlin is thriving, and the parts of the wall still standing showcase the work of local and international artists.

Where to look: While the Berlin Wall is the obvious place to go, the rest of Berlin also has a lot of amazing street art. Alternative Berlin even offers tours combined with a graffiti workshop in an abandoned margarine factory.

Upon realizing that parts of the city were a too drab, city officials launched the Paint Moscow project encouraging artists to take over the streets north of Moscow’s residential district. Teams of artists from around the world came to brighten up the city with their work, and to ignite an appreciation for what was once looked upon as “dirty graffiti” (though politically-charged pieces can still be very controversial).

Where to look: Northern Moscow around the Babushkinskaya metro station is the best place to browse the best of Moscow’s street art. There you can find works from some of Russia’s most famous street artists, including P183, who is best known for creating a giant pair of glasses with a street lamp.
