To access to manage the symbolic dimension. A citizen right

To give meaning to urban space is one of the most relevant activities to allow its conversion into public space, in turning sites into places. For this, it is essential to expand the concept of "accessibility" to the level of "symbolic accessibility" and understand it as one of the new urban rights. The article develops the concepts of "symbolism a priori" and "symbolism a posteriori" as intervention strategies of meaning of the public space. The first responds to the usual operations from the administration, the second to the popular processes of appropriation of space. Analysing the experience of creative participation - today in progress - in the Barcelona neighbourhood of Bon Pastor, the article raises the possibility of creating a meeting place between the two types of symbolism, through processes of co-production of public space, specifically its co-design.
