A breakthrough LiDAR (Light Detection and Ranging) survey conducted in the remote high-altitude valleys of the Atlas Mountains has identified a sprawling network of previously unknown Berber hillforts dating back to the 1st century BCE. The mapping reveals a sophisticated defensive landscape consisting of twelve interconnected stone citadels, each strategically positioned to overlook ancient caravan routes. This discovery suggests a much higher degree of political centralization among local tribes than previously documented during the period of Roman expansion in North Africa.
The most significant find within the survey is a series of massive, rock-cut terraced granaries that utilized complex subterranean ventilation to preserve grain for long-term storage. These structures indicate a highly organized agricultural surplus system designed to sustain large populations during times of conflict or drought. Researchers at the University of Marrakesh believe this 'fortified belt' served as a primary hub for the trans-Saharan trade in salt and gold, operating as a sovereign mountain state that interacted extensively with the Mediterranean world.
