<p>The proposed research aims at a comparison of the main historical surveys conducted on the Porta Palatina by different authors, with the data of a current digital survey. Through a work of redrawing and superimposition of information deducted from historical drawings, the analysis will highlight the consistency, discrepancies and inconsistencies of these drawings compared to the current state of the artefact. Therefore, the instrumental survey, necessary for the subsequent stages of graphical analysis, was carried out using photogrammetric techniques and Metashape software.</p><p>The drawings taken into consideration for this work are those by Sangallo (1494–1497 ca.), by Palladio (1566 ca.), by Promis (1869) and by D'Andrade (1883): they constitute a very interesting documentary heritage, although heterogeneous, in which qualitative drawings (Sangallo), scaled drawings (D'Andrade), measured drawings (in vicentine’s feet for Palladio, in meters for Promis) alternate.</p>
