The relief of the Porta Palatina: a comparison between different survey methodologies and representations

Within the historical urban fabric of Turin, the Porta Palatina is the most conspicuous part of the Roman boundary walls and towers still preserved: the research proposes the analysis of an architectural monument that belongs to the cultural heritage buildings, linking integrated survey techniques and representation methods. This work starts from Survey and History of Architecture courses carried out by the teaching staff of the Department of Building Engineering and Territorial Systems of the Politecnico di Torino (DISET); the Department of Land, Environment and Geotechnologies (DITAG) organised the metrical and instrumental survey steps. The research evaluates different results of the survey, focusing on contents, the restitution scale, the relationship between symbol and reality, taking into consideration user needs and pinpointing the time required with each method.
