ABSTRACT: The subject of this research paper, the open-air museum, we consider that especially in contemporaneity it becomes a main actor on the cultural scene, and through the current study we aim to create extensions of this type of exhibition, extensions that meet the needs of the general public. Moreover, through this paper we aim to systematize the fundamental pillars of vernacular architecture and heritage, but this time, not treating the subject in an exhaustive way, but pointing out its key elements through a series of projects that are currently work in progress. Although through this study we aimed to interrogate only a certain type of exhibition, in this case the open-air museum, in reality, we came to new interrogations involving actors from new areas of expertise, areas that we did not anticipate very clearly at the beginning of our research. Thus, we can say that at this moment, the research includes three pillars of work, pillars that we have built based on a methodology for investigating a type of architecture, perspectives based on which we try to build the body of this research. Of course, they are in a process of transformation, based on examples and certain typologies, so that we can answer questions and, why not, launch new questions.
