Street Art(?)
Following the 1974 revolution Lisbon was flooded with graffiti (most of which, political). The late 1980s and early 1990s brought the international trend from other world cities, with spray-paint taking over many of Lisbon's façades. The city currently suffers from a major graffiti epidemic, especially in the Bairro Alto district, the nightlife mecca that naturally also attracts the rebellious youth. Most of that graffiti is merely "tags" (or quite frankly, scribbles) on the walls, but in between all of those there are some quite amusing images. There is a new form of stenciled graffiti that could actually quality as closer to art (or at least artistic expression), as well as some (humorous) leftist propaganda.
If there is a bright side to this graffiti is that it rubs off a certain vibrant, youthful energy to the city...
