Within the framework of the PCR set up by Didier Josset (Inrap) and Viviane Auboug (SRA Centre Val-de-Loire) on the city of Blois, entitled “Blois : ville et territoire ligérien depuis les premières installations humaines jusqu’à nos jours” (Blois : city and territory of the Loire from the first human settlements to the present day), we carried out an inventory of the built heritage in the Vienne district, located on the left bank. This survey was carried out on a parcel basis and was completed by rare visits to buildings. The main objectives were to identify the buildings by architectural period, in order to understand the stages of formation of the urban fabric, and to identify the archaeological potential of these ensembles in order to propose keys for heritage management. In order to do this, it was necessary to construct a reading grid and local architectural references, in order to objectify the results obtained.
