This book presents, through the finished works of a considerable number of Catalan architects (among them; Bonell i Gil, Enric Miralles, Carme Pinós, Carlos Ferrater...) , the vision of a phase between 2004 and 2009. This publication aims to spread the work of these architects, while defining the informative and cohesive task of the Col·legi d"Arquitectes de Catalunya (COAC, Architects" Institute of Catalonia). Portrait of a Time, forms part of this trajectory, as well as constituting a point of inflection in various respects. It actually forms part of an even longer trajectory that began in 1874 with the constitution of the Associació d"Arquitectes de Catalunya [Architects" Association of Catalonia], which handed down to us an architectural documentation centre of which we are justly proud. Our Historic Archive houses the professional holdings of some 120 architects whose work is vital to an understanding of the history of Catalan architecture.
