Persianes lliures is a platform that tries to free public spaces in order to give them an exposititory use. This initiative is open to everybody; we try to give free access to art with a philosophy of continuous renovation, repainting once in a while the shutters that had already been painted. The aim of this project is to encourage citizens and neighbours to provide spaces to give urban artists the freedom to free express themselves. All of those who own shutters or private walls are welcome to adopt a work of art that will revitalize the neighbourhood. This will enable us to trade the current standardized, dreary or degraded facades for colourful, captivating murals that showcase the talent of local artists. This is an important step towards democratizing art and setting it apart from the profitability calculus.
