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.
