The churches of Alto Gállego

Abstract

[ES] The research focuses on the group of churches in the Alto Gállego region, north of the province of Huesca, known as “Iglesias del Serrablo”. The uniqueness of the complex and its architectural value provides a very important asset to the architectural heritage of the area. The “Amigos del Serrablo” Association, founded in 1971, has been valuing this heritage since its inception through its rehabilitation; however, the limited information and studies carried out on these properties mean that many of them are still unknown to the general public, despite the routes proposed by the Association for their dissemination. The research that is being developed analyses this group of churches from different areas: geopolitical, historical, geographical, orographic, etc. also providing an architectural study that helps technicians to address rehabilitation projects. In order to develop the architectural analysis of the properties, a virtual model is created using tools such as a 3D scanner, drone flights and a camera; which, subsequently, through the application of techniques such as photogrammetry and point clouds allow us to obtain the 3D model of the churches studied. With the digital model of the church, the investigation will be approached in two lines: a more technical one in which the geometric documentation, lights, construction and structural elements, dimensions, etc. are analysed. that serve to establish hypotheses of virtual reconstruction of those churches that are in ruins, or that help to establish a line of action to rehabilitate. On the other hand, the digitization of the building allows the creation of graphic representation support such as virtual reality and augmented reality that favours the dissemination and accessibility of this architectural heritage to a wider public, both in person and virtually.
