Abstract
All the feelings that animated the French population after the Second World War were certainly felt in Brittany, but there were also those instilled by an inter-war period marked by regionalist, autonomist and sometimes even separatist militancy. Whether willingly or faced with a fait accompli, the world of architecture played its part, formulating hypotheses and wishes that were able to take advantage of the "monstrous opportunity of war" to materialize. Various organizations were set up, some of them associations (Institut Celtique de Bretagne), others set up by the French state as a counterweight (Comité Consultatif de Bretagne). They strove to steer the debate and forge the framework for architectural production in line with their idea of Brittany as the master of its own destiny. But they also tried to establish themselves as the guardians of the profession, notably through the regional council of the Order of Architects. The many upcoming reconstructions obviously offered a considerable prospect for these aims, which were able to avail themselves of protectionist virtues.
The paper will briefly review the genesis of these intentions, then present the vectors imagined for their implementation during the war, often with the benevolence of the occupying forces, but also with the participation of personalities of national stature (Georges-Henri Rivière, André Dézarrois). Finally, she will reflect on what happened at the end of the conflict.
