Earthen Architectural Heritage in the Gourara Region of Algeria: Building Typology, Materials, and Techniques

This article investigates the status of earthen architectural heritage (EAH) in the Gourara region of Algeria in light of contemporary developments and the sovereign decisions taken by the Algerian state, specifically the upgrading of the region to a wilaya (province) in 2019, and the accompanying direct impact on the oasis system, which is renowned for its fragile character. The research started by focusing on perplexing questions: What factors contribute to the region's abandonment of earthen architecture? Moreover, could documentation serve as the optimal method for its preservation? In an attempt to explore and comprehend this distinctive heritage, characterized by its diversity, durability, and sustainability, this heritage has been linked to identity and local civilization dating back to prehistoric times, with evidence of their existence still present. Following a research approach and with the prospective purpose of preserving these buildings and what remains of them, the associated skills, materials, and construction techniques used in their development were investigated based on a descriptive, analytical, and documentary historical approach. Finally, the authors interviewed several qualified builders to collect knowledge of the local indigenous building practices. The research findings suggest that there is an urgency to consider a new perspective and strategies to preserve and protect EAH.
