Barcelona’s intersection par excellence is not meant for any specific community but rather a meeting point for all communities. From residents of every culture to tourists from every destination, from passers-by taking a rest there to people meeting up there to continue on their way, and all those crossing it from and to any direction. And including the pigeons, its local, daily inhabitants. To speak of tensions, gatherings and inter-cultural spaces in the 21st-century city is to set up these intersectional spaces which enable visibility to be brought to this public space in all its complexity, juxtapositions and friction.
