I have always loved this city.  From the first time I stepped foot on its grounds.  I felt an immediate love of art here and a need to show it off.  This is also true of the street art displayed all over the place.  Although the bulk of the art is centered around the Raval, Born, and Gothic Area of the city anywhere you go you will run into bits of stickers, posters and more.  The beauty of this is that it is free.  On a Sunday afternoon while the shops are closed one can easily walk around the city and appreciate the beauty of the persianas/shutters the work that went into making your Sunday afternoon walk pleasant.
