The Arquia Foundation aims to promote and encourage cultural activities in the field of architecture. Among these activities is the arquia / thesis collection, aimed at editing and publishing doctoral theses on Architecture, relevant for their contribution to architectural knowledge, once reviewed and adapted to the editorial line by their respective authors. The arquia / thesis collection thus seeks to make available to the interested public, in architectural research, a valuable material that, otherwise, would be difficult to access. With the intention of expanding and enriching the editorial fund of said collection, the Arquia Foundation announces this biennial contest aimed at the selection of unpublished doctoral theses in Architecture. This time 2 awards and 4 honorary mentions were granted, among 7 finalists, 14 preselected thesis among181 entries.
