Abstract
This study evaluates the effectiveness of Algeria’s Law No. 98-04 in protecting archaeological heritage through the case of the Tahouda site (ancient Thabudeos) in Biskra Province. Using legal analysis, historical contextualization, topographic survey, geophysical prospection, and field observation, the research identifies a persistent gap between the law’s provisions and their implementation. Results show advanced material degradation, outdated documentation, weak monitoring, and fragmented institutional responsibilities. The study concludes that effective protection requires updated GIS-based inventories, clearer conservation guidelines, decentralised management, improved interministerial coordination, and stronger involvement of universities and local communities.
