The objective was the temporary occupation of non-built sites in the Old Town, both privats or publics, offering different temporary uses in order to reach a 100% use. All these energies converged in the program “estonoesunsolar” that collected proposals from architects, groups and associations of residents, and that was channelled thanks to the institutional support, the Municipal Board of the Old Town and being managed by Sociedad Municipal Zaragoza Vivienda. The suggestion of the emptiness, the hollow place, the invisible and the silence has been valued. These temporary swellings of the fabric of the old town is a dynamic and changing (temporary) tool allowing us an alternative and flexible reading of the city and the public space. Empty spaces are trusted as a force for creating situations and events. Different agents and complex relations converge in every empty plot of land. This aspect has implied a mixing of complex and intricate agreements with owners. The program began in 2009 in 14 plots in the Old Town and then in 2010 was extended to the all city, recycling other 14 urban voids in public space.
All these ideas have finally crystallised in concrete interventions. Every non-built site contains an idea; every space is the wish of the residents before the “unreasonable silence of the world”. All the proposals have emerged from processes of citizen participation. A bet has been made on “immaterial” ethereal solutions expressing the provisional character of its presence and establishing dialectics with the already built surroundings through lightness. Every one of the 14 interventions has been a meeting point for citizen’ s requests and the landscape. An intervention has been made on the banks of a re-evaluated river serving as meeting point for children, youngsters and old people. Another intervention has been placed in a half-point between an Alzheimer centre and a centre for children. Work has been done using the concept of memories and the memory. Another action has been implemented in an edge point of the city, in its meeting point with the landscape through different urban orchards that melt with the surrounding landscape. This has been made in every non-built site strategically chosen. 32,000 m² of public (transitory) space has been added to the city.
Two years after launching the program “estonoesunsolar”, it can be affirmed that its objectives have been widely reached. The processes of citizen participation in the many targeted non-built sites have been “implemented”, 28 empty plots and 42,000 m² of public space have been added to the city. Interventions in depressed areas has been the excuse to draw up strategies of social cohesion. The objective in all of these areas has been to revitalise the city with uses and parallel activities, planning these spaces as places for participation and exchange. On the other hand, the citizens have received these processes as if they belonged to them, producing an intensive implication in all the stages of the projects. This program has also served to activate an employment plan for people suffering a risk of social exclusion (110 people has found a job). There have been many difficulties, from a very tight budget to those deriving from the intense and complex social and personal relations but all of them have served in the end to activate creative processes from complicity and hope.
