Revalorisation of Heritage Cultural Landscapes Through an Approach Based on Intangible Atmospheres

Abstract

This research examines fragmented heritage approach, which often overlooks intangible dimensions and resident involvement. It introduces the theory of atmospheres as a conceptual framework to improve rehabilitation of historic urban fabrics by focusing on inhabitants. The empirical study, conducted in a fragment of the Casbah of Algiers, combines semi-structured interviews with 70 professionals and a qualitative investigation of 28 residents through guided walks, mental mapping, and photo-elicitation. The findings highlight that heritage atmospheres are manifested through their appropriation by residents, which is conditioned by the dynamic interaction of four dimensions: social, symbolic, sensory, and spatial. A significant divergence is observed: while professionals emphasise the spatial dimension, residents place greater importance on the social and symbolic aspects. Historical richness promotes attachment, whereas significant spatial changes lead to disappropriation. This research validates the inclusion of a symbolic dimension in atmosphere theory and proposes innovative cartographic tools to guide inclusive rehabilitation efforts.
