Sobre exposiciones de arquitectura y sobre arquitectura de exposiciones: un ejercicio de enfoque
The twentieth century can be regarded as the golden age of architecture exhibitions. The special vicissitudes that have turned these hundred years into one of the most turbulent periods in the history of the discipline provided a fertile ground for the growth, development and success of the exhibitions. To the extent that it is impossible to separate the exhibition phenomenon from the deep process of transformation experienced by the architecture over the last century. And so, regardless to what one would consider, the exhibition appointments were not limited to gather the most relevant events of the period, but were made by themselves as relevant as any of the selected contents to be displayed.
Therefore it is considered that the study of exhibitions, defined as a relevant phenomenon for architecture, may help to understand some of the key elements of the history of the discipline in the previous period. On one hand, the contents accounted milestones or border moments with the capacity to deeply transform the course of architecture, in many cases permanently. On the other hand, large contests involved extraordinary opportunities for direct creative experimentation with the buildings that had to house selected pieces, although the resulting architectures were contaminated by the very specific characteristics of the samples. 
In this context, the article focuses on the revealing and paradoxical relationship between container and content. To that end, given their unavoidable interdependence, a method of study based on an exercise of dual approach is proposed. This approach allows us to study the phenomenon in both ways, exploring each one of the parts without losing sight of the relationship between them. This method has been carried out by the School of Architecture of the University of Navarra for the last two years. Thus, architectural exhibitions and architecture of exhibitions, were analysed by an ambitious initiative consisting of various actions and culminating in the IX International Congress of the History of Spanish Modern Architecture. Some of the results of this ambitious research project are reflected in this article.
