This project emerges from within a complex urban story. The area has been badly affected by slow infrastructure development and suffers from low quality social housing interventions by the state in the 70s. The area is dominated by a sophisticated modernist road network and an overwhelming slum, the inhabitants of which are skilled at integrating their local knowledge with new waves of culture. Add to this a strong military presence (Fuerte Tiuna military base) and all of this combines to create an intricate geomorphology. In the middle of this complex structure, Tiuna El Fuerte Cultural Park was developed. Promoted by local artists and a significant number of urban activists, the park managed to occupy an old and abandoned parking lot thanks to a legal loophole that allows for the use of unused lands under a bailment structure (that is, without transfer of ownership) for twenty years. Out of this first community action sprang a whole chain of cultural ones, which progressively transformed the inactive ground into a sophisticated support system for the collective dynamics of the community. The space experiments with various administrative, organizational, operational and political formats (foundations, companies, social enterprises, NGOs, collectives, groups and investigation labs), employing as a participation methodology an internal weekly assembly during which basic items of maintenance, entrepreneurship, and project formulation and revision are discussed, as well as other issues such as systems for the exchange of values and information, alternative pedagogy, and a productive and autonomous society. The space and its infrastructure (workshops, classrooms, radio station, recording studio, video and communications rooms, Library, auditoria and a small cafeteria) are open to the public and only require that participants develop educational and formative programmes in line with this ethos.
