Valparaíso is South America's street art capital - an open-air museum where every staircase, walkway, and wall tells a story. From political murals of the Pinochet era to contemporary masterpieces, art covers every surface. Cerro Polanco became a hotspot since the 2012 Polanco GraffFestival. Spanish artist Cuellimangui has become a local legend with his colorful monster tessellations. Wander the Galvez passage in Cerro Alegre and Paseo Yugoslavo for the best concentrations, or hire a local guide to discover hidden gems and learn the stories behind the art.
