For some thirty years, a handful of architects has been trying to call into question the primacy that the history of architecture has given to monumental buildings. The representatives of this trend want to get away from the short chronology, common since the Italian Renaissance, and react against the dominant international functionalism that has too little respect for the local cultural contexts. It is under the influence of this “vernacular” approach that the small traditional structure became as legitimate an object of research as the well-known buildings. This approach, innovative and audacious as it was, broke with a Utopian vision of a large part of modern architecture. It led the architects concerned to turn toward non-European countries and to focus their attention on the connections between indigenous housing patterns and cultures. From this decentralization ethno-architecture was born by which we understand the study of preindustrial, “traditional” habitats and housing. Inspired by Panofsky, Eliade, and Lévi-Strauss and familiar with the social sciences, these researchers appropriated the conceptual tools of anthropology. They opened up important fields of research in Asia, Oceania, the Middle East, and Africa and reaped a rich harvest of ethnographic materials. It quickly became clear to them that the so-called “traditional” house developed, in imitation of palaces and temples, from the culture of a given population and that it was informed by the religious images of the inhabitants as much as by its most sacred buildings.
