But, taking advantage of the potential magnitude. This reflects the evolution of resources and in the collaboration between the Technical School of precepts of the graphic documentation, but also the Architecture (ETSA) of the Rovira i Virgili technological limitations inherent to each historical University (URV) and the Catalan Institute of period.

These documents already show the incidence of Aware of the deficiencies in the graphic the monument in the configuration of the topography of documentation of the Roman circus of Tarragona, it the city’s historical precinct. And, on the other hand, was decided to choose this monument as an area of starting with the professionalization of archaeology in methodological test, where the students of the the 1980’s, the planimetries obtained in subsoil subjects mentioned above have developed their excavations have proliferated, even though numerous practical works. and old urban reforms have caused irremediably patrimonial destructions, in some cases.

At an urban and Archaeology (ICAC) in the field of architectural historical level, three processes stand out. The first heritage. The School's interest in expanding its research has been the stratigraphic superposition on the and academic horizons has required looking for Roman remains, produced from the urban reforms of interdisciplinary work spaces, on the one hand, and the medieval period. It was during this period that the developing a research niche in which to develop and major transformations took place, as a new road disseminate its own "personality", on the other. This network was created that compartmentalized the will has led them to the territories of archaeology, and circus arena and created a new circulation structure. especially to all that concerns the subdiscipline of Some streets were traced inside the arena, and others “archaeology of architecture” and “archaeology of over the old stands defining the current urban construction”. In this framework, architects contribute appearance. While both these processes occurred on their technical, constructive and drawing knowledge, the outside of the architectural remains, a third one while archaeologists provide the historical context and occurred in the very inside of the Roman building: the its descriptive and stratigraphic rigor.
