BUILDING AN INTRINSIC PROTECTION OF 20TH CENTURY ARCHITECTURAL HERITAGE IN MARSEILLE: A TOOLED METHODOLOGY FOR KNOWLEDGE ENRICHMENT

Abstract. The French 20th century heritage is in a situation of obligatory change within the framework of a societal transition. However, this change must be accompanied by a careful and precise look at the building so as not to lead to a complete banalization of the specific architecture of the different trends of the 20th century. These transformations have already started and are not dependent on research or patrimonialization for implementation. Technical solutions alone pose significant risks of architectural missteps. Thus this paper introduce a tool-based method for the production of systematic knowledge on this fragile "heritage". By applying it to a corpus of seven collective housing operations of the 20th century, as a framework for observing the development of analysis criteria, shaping the tools and confronting the reproducibility of the method, this paper seeks to present the proposals of objectification of gaze and memory, in an approach of openness and diversity of the knowledge (interdisciplinary scientifically, but also profane). Whether through dedicated visual representation or the use of conceptual models such as CIDOC-CRM, the ultimate goal is to examine the emergence of intrinsic protection for 20th-century architectural heritage by providing inhabitants access to the architecture and the knowledge produced through its objective analysis and explicit qualities, thereby enabling their acculturation. The objective is to question the perceived appearance of such protection.
