The mid-sixties saw a growing concern among architects for the rapid destruction of architectonic heritage as a result of economic expansion. In the cities and along the coast, buildings, enclaves and landscapes were disappearing fast in unregulated fashion. The reaction came in the early seventies; a group of architects at the Col·legi d’Arquitectes decided to take action and start recording threatened heritage. They began to collect images and original plans, producing catalogues of elements in need of protection, and they approached the Government to exercise their democratic rights as far as the regime of the time allowed… and this is how the History Archives of the Architects’ Association came into being, starting out as a Documentation Centre. This initiative on the part of the Association in Barcelona soon spread to the other Branches. In Girona, there are documents dated as early as 1970 for the project for what was to be the future History Archives-Documentation Centre, initially based on the documents of Girona’s noucentista architect, Rafael Masó i Valentí. Today the History Archive-Documentation Centre of the Girona Branch is a service including the Association’s Archives — covering the Branch’s work since 1932 — and the History Archives, which contain the Documentation Centre’s information on a variety of supports, to provide professional and academic assistance for Association members and the general public.
