3. THE CATALAN CONTEXT
The  development of sports practice is inherently commingled with the social and  political conditions of the country. The sport's historian Sixte Abadia Naudi[5] compares  the democratic transition of Spain to the dissemination of sports practice “para todos”. \cite{Abadia_Naud__2015} In the first period,  1975-1979, sport associations are the main promoters of the indispensable[6] reorganization  of leisure activities. From 1979 on, it is the charter of self-government which  stated that sports policy would be the exclusive competence of the Generalitat,  so for the first time during peacetime, this regional Catalan institution was  able to organize sports. In the same year the Manifesto, edited by Asociaciones de Vecinos de Barcelona, finds  the main set of problems of the city, among which                    
Sports equipment should be obtained, deprivatizing sports areas, to municipal ones, rearranging free zones for the construction of new equipment for the practice of sports. It will be extremely important to coordinate actions with school, cultural and sports facilities. \cite{AA.VV__1979}
This quotation  clarifies that the understanding of sport they are looking at is the one of  "deporte para todos" (sports-for-all)  to be integrated with the educational and cultural ones (functional  integration). Sport is  considered to be part of a system of basic equipments, to be included in a plan  to rehabilitar[7] (to rehabilitate) the city  that is already built[8] \cite{Bohigas__1985} \cite{Bohigas__1986}.  Therefore it is important that it is reached a widespread diffusion of these  facilities within the city and that they are linked to other services as well  (for example, a civic centre or a school).
Within the  literature on the subject of Catalan sports architecture a text particularly  relevant to the research's frame is Barcelona.  Arquitectura y ciudad 1980-1992,  introduced, among others, by an essay by Oriol Bohigas[9].  In Arquitectura deportiva en Cataluña two are  the main issue among which the author focuses: the role played by the Sixties  generation and the antecedent of the Escola de Mar. \cite{Bohigas__1990}
In relation  to the Sixties generation, made by the generation of architects graduated  during the Sixties at the Escola Tècnica Superior d'Arquitectura de Barcelona  (ETSAB), Bohigas identifies within a geographical and temporal unit, a  diversification of the architectural panorama resulting from a contamination of  classicism, systematic plainness, minimal adornment, etc. It is to demonstrate  that in the face of technical limits provided by the public administration, the  expressive autonomy of  designers is  achieved. 
In relation  to the antecedent of the Escola de Mar, which will be better analyzed later,  the author identifies the relationship sport-public customer. Understanding the  role of the public equipament[10]  (equipment) is central for research purposes: sports architecture is  part of the group of public equipment, strategic issue for urban rehabilitation  projects. \cite{AA.VV__1983}                 
Compared to the research themes, Bohigas' text reiterates  some crucial issues, among which: 
3.1 RESEARCH TOOLS AND METHODS
Bibliographical and iconographical research on the catalan context  was done according to tools described above, as:
The collected  bibliographical and iconographical materials was organized according to the  method above described: reasoned bibliography organized by issues; register of works; filing of a selection of works;  interpretative re-drawing of a case-study (during the next months it will be done  for a wider selection of case-studies).
These  materials are the annexes to this paper. 
 
3.2 THEMES
Through the research done so far, it is possible to identify some  key-themes: 
3.2.1 Public  equipment in Catalunya
Taking back the periodization  that the historian Sixte Abadia Naudi identified studying the process of democratization of sport practice in  the Catalan region it is possible to understand the deep relationship between  political choices and the development of sports practice.    This theme, or the  relationship between public amministration and politics of sports development,  is the argument of the text La ciutat  de les anelles by Enric Truñó \cite{Truñó__1987}. The author, to describe the process that brings  Barcelona to host the XXV Olympic Games, points out some key-dates and  enforcement measures related to Generalidad and Ajuntament decision about  public architectures.    With a view to the  research it seemed useful to system this information with, on one hand, the  architectures that represent the implementation of the politics decision, and  on the other hand, the publications that outlining the relationship  architectural design and urban strategy.    This chronological  order is taken to draw-up the following table that correlates: architectures,  key-dates for public institution and enforcement measures, publications.
