Multiple 3d Approaches for the Architectural Study of the Medieval Abbey of Cormery in the Loire Valley

Abstract

ABSTRACT:This paper will focus on the technical approaches used for a PhD thesis regarding architecture and spatial organization of benedict abbeys in Touraine in the Middle Ages, in particular the abbey of Cormery in the heart of the Loire Valley. Monastic space is approached in a diachronic way, from the early Middle Ages to the modern times using multi-sources data: architectural study, written sources, ancient maps, various iconographic documents… Many scales are used in the analysis, from the establishment of the abbeys in a territory to the scale of a building like the tower-entrance of the church of Cormery. These methodological axes have been developed in the research unit CITERES for many years and the 3D technology is now used to go further along in that field. The recording in 3D of the buildings of the abbey of Cormery allows us to work at the scale of the monastery and to produce useful data such as sections or orthoimages of the ground and the walls faces which are afterwards drawn and analysed. The study of these documents, crossed with the other historical sources, allowed us to emphasize the presence of walls older than what we thought and to discover construction elements that had not been recognized earlier and which enhance the debate about the construction date St Paul tower and associated the monastic church.
