One of the unique thing that reminds me of Lisbon is, its street art. Many buildings in the business district have decorated walls with mural art and graffiti. We were told that the Lisboners self-expression increased, after the democratic revolution in 1974. Before the democratic revolution, coloured tiles were widely used on buildings and roads. Many coloured tiles walls can still be found around Lisbon even now. These are few photos taken during our trip.
