The session questions old and new virtual materialities in the History of Architecture and Urbanism: architectural surveys of building archaeology, photogrammetry, laser scanning, geomatics, etc. This materiality influences the perception and analysis of space, but to what extent?

The first axis focuses on the history of the dematerialization of space for analytical purposes. While researchers specialising in the study of the Medieval period (especially building archaeologists) traditionally use reconstruction techniques, various Cultural Heritage study centres (within academia or not) have in particular used these techniques, essentially up to the limit of Modern and contemporary times. How, over the long term, have these techniques influenced the perception of space and therefore conditioned the analysis of buildings? Where (university departments, local authority heritage services, heritage conservation organisations, etc.) and by whom (photographers, surveyors, draftsmen, etc.) have these techniques been implemented? Finally, can we establish correlations between the evolution of these techniques and that of historiography?

The second axis focuses, always for analytical purposes, on the extension of the dematerialization of space since the ‘digital revolution.’ Medieval buildings are thus no longer the only concerned, but also those of later periods, as well as an entire area, whether urban, peri-urban or rural. The advent of digital technologies has brought a revolution in the perception of space, creating new methods of analysis. Which new materialization techniques have mostly influenced researchers in the history of architecture and urbanism? Have these techniques constituted a real revolution in analysis or are they only incidental tools for materializing space? Where and how are these techniques applied? What new techniques should evolve in order to further improve the analysis of buildings?
