Along with my love of the Barcelona Balconies, was my obsession with the doors. My daughter got so tired of me stopping and taking pictures of doors. I didn't get too many strange looks though. I think doors are interesting to more than just me. Hopefully they are interesting to you as well.
There is lots of graffiti in Barcelona. While part of me doesn't like that someone does this to property, the other part really enjoys the artfulness of it.
