Buenos Aires, Argentina

Buenos Aires has one of the most vibrant and legally tolerant street art scenes in South America, with the Palermo neighbourhood serving as the city's unofficial outdoor gallery — home to towering portraits by Jaz, wheatpaste works by Martin Ron, and the politically fierce imagery of Run Don't Walk. Argentina's economic crises and political turbulence of the 2000s gave the city's street art a raw urgency still visible in works that skewer corruption, inequality, and state violence. The city hosts organised tours of its best pieces, and many property owners actively invite artists to paint their buildings, treating murals as a form of neighbourhood investment.
