Preserving built heritage in Algeria: overview of Imedghassen's restoration and conservation actions (1873–2018)

Purpose The purpose of the paper is to outline the impact of conservation works on Imedghassen heritage values in relation to the changes in the Algerian built heritage conservation legal framework, within a timeline marked by two main periods: French colonisation (1830–1962) and post-independence (since 1962). During this period, the Algerian heritage conservation context has experienced several shortcomings arising from a limitation of professional skills development, regulatory guidance and in-depth knowledge of ancient building materials and techniques. Thus, Imedghassen, the oldest royal mausoleum in North Africa, has undergone much damage that was hardly managed due to inadequate guidance for an effective management system. Design/methodology/approach By identifying Imadghassen's heritage values and attributes, the approach aims to assess the impacts of conservation works on these attributes while relating each action to the Algerian legal and regulatory framework of the time. The main research material is derived from the Algerian legal and regulatory framework and international guidelines and policies on cultural heritage conservation. Imedghassen's conservation works and direct observation focused on building materials, their use, balance and position in the overall structure. Through discussing the conservation of Imedghassen as a case study, some insights will be presented into the efforts made by Algeria in maintaining its built heritage asset through all the challenges it faces as an emerging country. Some critical issues will also be highlighted concerning the conservation process to be taken into consideration in further similar contexts. Findings The paper argues that conservation actions employed an ineffective theoretical approach to clearly understand and identify the heritage property values, thereby endangering the building's authenticity and integrity. Originality/value The paper outlines the limits and challenges of each conservation project undertaken on Imedghassen and their impact on its values while considering national legal and regulatory instruments and international guidance on built heritage conservation.
