There's more to Portugal's second city than port wine, scenic beauty and traditional tiles - Porto's cutting edge street art is impressive in both scale and detail
Street art can take on a political slant - this striking piece depicts the fall of the United States of America with a girl dressed in the Stars and Stripes, looking at a fallen Statue of Liberty.
This artwork is part of a local project to commemorate some of the local residents. The lady depicted was always very well dressed and used to grow the most incredible rose bushes.
Other pieces take aim at famous people; this one shows displeasure at footballer Cristiano Ronaldo and his golden balls.
There are many different ways in which street art is created, from freehand paints and aerosols - which are the most common - to intricate stencils such as the two above from French street artist Guaté Mao.
A more unusual method is that shown by international artist Vhils who has removed the white plaster of the building to create this artwork below. He often uses explosives to achieve this effect!
Street art can depict serious subjects or the more whimsical and surreal aspects of life. The piece in the top two images shows a large stencilled mural by Daniel Eime which depicts the older generation that suffered in silence during the dictatorship of António de Oliveira Salazar from 1932 through to 1968. Whilst the bottom two show how street artist Kalif visualises Porto's steep hills as different levels in the Mario computer games.
Styles vary hugely from artist to artist as the above two images show. Porto native artist and tattooist Costah is well known for his colourful cartoon style, while international artist Hazul uses secondary shading to give the image a real 3-D feel.
The largest Hazul Luzah mural in Porto (at the time of writing!), it's easy to pick out common subjects, including the faceless Madonna, the tao symbol and various other ancient symbolic imagery. All with Hazul's typical 3-D feel.
This mural, just behind the São Bento train station shows Hazul's love of symbolism, including the trident, ancient fertility symbols and Hazul's trademark 3-D style.
