The objective of this project has been to initiate the studies of late-antiquity architecture in the north-eastern Tarraconense from the perspective of the construction techniques and materials. The first step has been the graphic documentation of diverse urban and rural buildings, with the aim of establishing a relationship between the construction features, the socioeconomic setting of the building and the underlying cultural context. In addition, the graphic documentation produced is the result of experimentation in the application and management of photogrammetric and data capture techniques.
